Suggested correction: People doing procedures change gloves all the time. There is nothing suspicious about using 2 pairs of gloves in 3 minutes.
He was already done with the procedure when he removed the first pair of gloves. He was never shown putting on the second pair.
It's the same scene replayed, a true editing error.
But this scenes are within about 15 seconds of time - so there is no time to put on another pair.
