Actually it is.
The purpose of this rmdir is to remove directories which are empty,
but leave around those which aren't such that you don't lose your
queued e-mail messages just because you happened to (temporarily?)
uninstall Postfix.
If you install Postfix but don't use it and just uninstall, then
everything gets removed cleanly.

This is very different: find is recursive. A similar effect to the
rmdir may be achieved with find -maxdepth 1, but I don't see the need.
