"Yes, it did", Reyerson said during the trial of former police officer Derek Chauvin.
Bystander video of Floyd crying that he couldn't breathe as onlookers yelled at Chauvin to get off him sparked protests and scattered violence around the USA and triggered a reckoning over racism and police brutality.
But he said once the 46-year-old was on the ground and stopped resisting, "at that point the officers should have slowed down or stopped their force as well", he told the jury.
Jody Stiger, a use-of-force specialist testifying for the prosecution, was questioned at the trial of Derek Chauvin, the white officer seen in a phone video kneeling on the neck of Floyd, who was Black.
"I vehemently disagree that that was appropriate use of force for that situation on May 25", Arradondo testified on Monday.
Chauvin, 45, who was sacked from the police force after the incident, has pleaded not guilty to charges of murder and manslaughter. He said police were justified in using force while Floyd was resisting their efforts to put him in the squad vehicle.
The May 25 incident a year ago triggered widespread protests against police treatment of minorities in the United States and around the world.
He also said officers were taught that restraint is considered force and that they must use the least force required because "it's safer and better for everybody involved".
Mercil testified that a neck restraint created to render a suspect unconscious neck is authorized only when the suspect is actively and aggressively resisting.

They were taken at different moments during Floyd's arrest, starting about four minutes after he was first pinned to the ground, according to time stamps on the images.
Under cross-examination by Chauvin attorney Eric Nelson, Mercil testified that officers are trained in some situations to use their knee across a suspect's back or shoulder and employ their body weight to maintain control.
Earlier in the day, Sergeant Ker Yang, a crisis intervention training coordinator, confirmed that Mr Chauvin had completed the department's 40-hour practical training course and his "ultimate goal" should have been to assess Mr Floyd's medical condition during his arrest.
Bystander video of Floyd crying that he couldn't breathe as onlookers yelled at Chauvin to get off him sparked protests around the US that descended into violence in some cases.
The officers also rebuffed offers of help from an off-duty Minneapolis firefighter who wanted to administer aid or tell officers how to do it. In this incident, Chauvin did not do so.
Minneapolis Officer Nicole Mackenzie leads the department's EMT unit and she testified that just because someone could talk does not mean they are not having difficulty breathing. He added that police are trained to use neutrality, respect and trust in crisis intervention situations.
Stiger testified that Floyd did not appear to have an opportunity to comply. A panicky-sounding Floyd struggled and claimed to be claustrophobic as police tried to put him in a squad auto, and they pinned him down on the pavement.
On Tuesday, the lawyer for George Floyd's longtime friend Morries Lester Hall said he is pleading the Fifth, in fear of self-incrimination.
Nelson told Cahill he planned to ask Hall whether he gave Floyd any controlled substances and why Hall left Minnesota immediately after the incident. Mr. Floyd's girlfriend, Courteney Ross, testified that she believed Mr. Hall provided drugs to Mr. Floyd but she had never witnessed the transaction. Even so, the judge said Hall should be able to testify on Floyd's condition in the auto and whether he fell asleep suddenly after possibly taking opioid pills. "So, what I'm going to do is I'm going to ask Mr. Nelson essentially to draft to in written question form, with the expected answer based on whatever statements were made, on what that would be".
