It would be wrong, though, or at least not have the same effect.
ItemPointerSetInvalid does not set the target to all-zeroes.

(Regardless of that detail, it's generally best to accomplish
objective X in the same way that existing code does.  Deciding
that you have a better way is often wrong, and even if you
are right, you should then submit a patch to change all the
existing cases.)
