Only that the drill doesn't know this. When it enters the board it won't
think "hey, lets enter a deflection further forwart to compensate for the
later movement, it will enter straight where it is at the start of the
hole.

It doesn't really matter a few mm up or down, but if the hinge is for
example too high the drill will enter, and then bend forward as it pivots
down. If the hinge is more or less the same height that's better.
