I saw that this morning too. Not sure if the girl in Black's video gets to this point (might be worth watching, but I don't want to spend a half hour on it...I'm assuming she discusses how scratch resistance=crack resistance)

Basically, yes.
IIRC, materials science says cracks usually start at scratches. Reducing the number and depth of scratches means reducing the chance that a hard material will crack. The picture pRICE posted from the flex test shows the typical flaw that hard materials usually don't flex/bend far without breaking.
