I don't have a save-excursion.
If your question is, why don't I have save-excursion, the answer
is
probably that I didn't understand save-excursion when I wrote that
quick hack decades ago.
I don't know whether it would work.
I think it wouldn't; because probably checkin/out deletes all the
existing text from the buffer (thereby pushing both point and mark to
the beginning) before inserting the new text.
Well but this behavior only happens if there are keywords in the
buffer so I am not sure about your explanation.
I have the feeling there is a (goto-char (point-min)) call
in the code, if there are keywords in the buffer. However I
have failed to find such a line.

VC has a habit of changing windows, IIRC. Mike changed the connection
between window point and buffer point a few years ago (this also
confuses VM). I suspect what is happening is that some work is being
done in one window, then when you go back to the original window point
is restored. It might also be that there are *too many*
save-excursions, or a save-excursion with incorrect scope, and point
gets restored to the wrong place after the operation is done on the
keywords.

Indeed.
I also have the following in my (antique) tame-vc-hacks:
; hooks so that window configuration is restored after checkin
(defun vc-checkin-save-window ()
(make-local-variable 'vc-saved-winconf)
(setq vc-saved-winconf (current-window-configuration)))
(add-hook 'vc-before-checkin-hook 'vc-checkin-save-window)
(defun vc-checkin-restore-window ()
(if vc-saved-winconf (set-window-configuration vc-saved-winconf)))
(add-hook 'vc-checkin-hook 'vc-checkin-restore-window)
