I'd say that in general the answer is "yes", with the caveat
that it might depend on the underlying operating system.  That is,
127.0.0.1 is an IP address, just like any other, and traffic sent
through that interface is IP traffic, blah, blah..

But, it is a "special" address in a sense, and I suppose the
OS might be allowed by the specs to treat that traffic differently
than "normal" IP traffic...

Still, I'd be highly inclined to think that for all practical
purposes you can assume that it does.

TTYL,
