But we're not talking of something that is highlighted "when you move
to another part of the code"; more like "when you finish the next
token in the line".

I don't have a performance problem, but font-locking isn't the fastest
of Emacs features. You have a 1,6 GHz CPU; mine is fast, too. But
Emacs is used in all kinds of computers. That said, if you write a
patch to make the font-locking more correct without sacrificing
performance, I'm sure it'll be very welcome.

Not really. Font-lock patterns have capturing groups for a reason
(that's what the 1, 2 in the next line refer to).
