If we're thinking of the same Mirror's Edge run, that was meant to be a joke and to bring to light the ridiculousness of a "glitchless" run as a lot of things can be interpreted as a glitch or not.
Interesting! Thanks for this; this happened just as I was getting into speed running, and I, like many others apparently, didn’t realize that, but I did some googling over lunch and it appears this was the case! Thank you for the extra context.
