While you are correct in principle, real world experience shows that
some systems work well with this setup.
I was able to change between wired and wireless in the middle of a
download without transfer stopping. I did confirm that both interfaces
had the same IP at the time.
I have no doubt that other systems don't handle this well and as such it
is not a recommended setup.
