Don't forget a fourth case (there may be others):

* Something is already mounted at /home/root/A and you end up mounting the
second device over the first, which will severely confuse anything already
trying to use /home/root/A

At the very least, I think you should create the mount point just before using
it, to avoid the above possibility.

Personally I would not use such an "active" approach to what you're trying to
do.
