My answer is the same. Some users write programs that explicitly support
calls under different versions. Sometimes you have to look inside to see
that; part of the art is often concealing the cleverness from the user.
In any case, anybody can call anything under different versions <= their
current Stata version; the question is whether it makes any difference.

To clarify, I know that lots of people like you will provide a
foobar8, foobar7, etc. when you release a new version. By version
control, I was thinking of how Stata does it, e.g.
version 7: foobar
which would cause foobar to revert to its version 7 behavior. I
don't know of any user written programs that do that, i.e most
programmers just seem to write a foobar7, a foobar8, etc. But, I
could be missing some.
