Damn: I've been trying to brainwash my colleagues to say "branch head"
or "latest head of X".  (The worst is that, for historical reasons
related to a misunderstanding of CVS terminology when the company
started using version control in 2001, everyone says "head" when they
mean "trunk".  I've almost cured this, although it took the switch to
Mercurial to really make it work.)

So, "branch tip" is short for "tipmost head of named branch"?  Sounds
right to me.

Sounds good to me.  At work, I have been telling people "forget about
tip, tip is meaningless" for 6 weeks now, and I think they've gotten
the message.
