I don't remember where I read this, but I think it was a usually well
informed source.

The system keeps a desktop file (or desktop database on newer systems) where
for every creator (read this as "for every distinct application" if you
don't know what a creator is) the location of the application is kept. This
is updated whenever you copy or move (?? I'm not 100% sure of this) the
application. So you're right, in general, the latest version is ran.
