It's no so much WordPress, as it is the hosts on which WordPress runs.

_Sometimes_ for _some_ users, copying a new file over top an old file
produces problems.  The site breaks, things don't work, whatever.

In almost all of these instances, deleting the original file first, and
then copying up the new file, solves the problem(s).

So the instructions to "delete first" were added to ensure a consistent
approach to trying to prevent this problem in the first place.
