The man is correct. Steele waves it off with 5 seconds to go on the clock in this clip. https://youtu.be/m9zKwGeHIgM?t=3057 Over the years the myth has grown that there were only 2 seconds left to go.
Steele said he didn't see the post light blinking indicating the last ten seconds of the round and having these isn't common where a ref would get use to them. In either case Steele said it was his duty to know when a fighter needed protection and not exactly when a round would end.
