No particular reason, other than avoiding direct use of globals when
you don't actually need them is always a pretty good idea.

Using a global means that you might modify the global accidentally,
and in this case, I had no need to modify the $post global.  On the
other hand, get_post() returns the same global post object anyway, but
now the $post variable is in the function context space, so if I did
accidentally modify it, then the result of that change would not
affect anything else.
