Nope. The plug is pre drilled with the tap drill, and locked in place. The
tap is then run in from below, where the pre-existing threads are undamaged,
and thus will segue into the insert with no problem, especially if it has
been fitted correctly at the lower end. You would indeed have a problem if
you tried to start the tap from the top surface.

Wouldn't there be difficulties in trying to get the threads to line up
this way?
