Yes, but in this case the "tokens" are called "names" (a single argument
consisting of a list of names, blank or comma separated).

That was my first impression, but since "argument" is defined as the
whole -o argument (see above), it is indeed the remaining of the whole
argument. If it was not, the text should say the remaining of the "name"
(token as defined in the first sentence).

The exemple may help since in the application usage, a "name" consisting
of "ppid=MOM" is put _last_ which matches Alan Barret's interpretation:

ps -o user,pid,ppid=MOM -o args

i.e. one must issue as many -o options as there are renamed fields.

This is subtle (and probably should have been avoided) but IMHO Alan
Barret got it right.
