The actual issue is that some, including Green, have had benches white lighted for what appears to be sinking/heaving AFTER the press command has been given.
The difference between heaving and not, for a bench presser skilled at the movement, is like the difference between a strict press and a push press. It's a very different movement. Your point that YOU suck at heaving is quite irrelevant. It just means that you suck at it. Kind of like how I suck at push pressing. I can get maybe 10 extra pounds out of a push press, but I know other lifters who get like 80 extra pounds out of it.
Also, your point about ROM vs. heaving is nonsense. I don't know why you thought it was anything but that.
