set-transient-map and a question

[T.V Raman]

set-transient-map is used in text-scale-adjust here:
https://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/face-remap.el?h=master#n423...

But it looks like it passes nil as the keep-pressed arg which sounds
counter to the documentation for set-transient-map; but
text-scale-adjust does work as intended  -- so am I reading the
set-transient-map doc incorrectly?
