I did some tests in real time and interestingly enough I was able to make game to reset and make Mega Man's speed to speed up for the rest of the screen, so that video is not a fake one. I'm just curious to know what's so different in that place because you can do things like that in real time, still not easily though. It's known you need a place where screens are connected and it seems that's exactly a place for that. This might help speedrunners quite a bit if they succeed well in that place :)
In our current run and in this stage we acquire magnet beam and perform DelayStageClear in the beginning so this won't help there.
EDIT1. Okay, after fiddling for a while I triggered something I've never seen with this game before. Mega Man zips like crazy in the air and in the end game just resets itself. Here's my .fm2 file,

EDIT2. Oh right, this was already used back in 2014 or so among the speedrunners, so this wasn't anything new. I must've hit my head somewhere because I was unable to remember anything about this.
Here are couple of players who used it in the past but soon credits glitch based runs beat these off the map.
