Yes, that's essentially correct.  However, there are a few nuances.

The _requested call at line 210 makes a call to _description, passing
along the (expl 'all expansions') arguments.  However, _requested doesn't
handle passing the additional formatting strings along to _description,
so it's necessary to drop those two arguments from _requested and make
an explicit call to _description instead, handling the "menu" style as
is done for "_requested expansions".

I note in passing that it doesn't make sense to have a tag-specific
format style unless one also has a group-name style, because in the
absence of group-name all the matches end up in group "-default-"
and all the format strings get displayed together above that, and
not necessarily in related order, which can be quite distracting.

As mentioned in users/21955, I don't understand why a single match was
being excluded from the expansions tag but included in all-expansions?
