Nope. It's the flex of the board when sheared. Less when cut, even
less if diamond cut or milled.
My understanding of a shear vs a shear/brake is that the brake part
allows bending metal, and therefore, is not relevant to the argument.

You need to hold the board against a straight brace and keep it from
wandering when sheared. Otherwise, a shear does a fine job. Good
lighting and layout marks on the board will help.
