Yes, you are right, I confused two things -- target refreshers are not related to record-routing, they update just remote target, thanks for pointing this out.
Anyway, you still don't know if message FOOBAR creates dialog.
Well, IMO absence or presence of tag in the To header field should be the definite difference between the two. INVITE which creates a dialg would be To-tag-less, while one that refreshes a dialog would usually have one. And if my memory serves according to the RFC INVITE is the only type of message which can create a dialog.
SUBSCRIBE messages also create dialogs. To tags probably could be used to distinguish such requests, nothing that would prohibit that comes on my mind right now.
