...which is not very different from a ttbb male choir template, so
I'll bite.

I wouldn't know.

Me neither, and I *have* sung stuff that has different time signatures
in different staffs ;)

But I'll comment a bit more:

You probably want \context ChoirStaff here (and so does satb.ly; using
StaffGroup is a bug, IMHO).

Some day, I wish someone could explain to me what this does, 'cuz I
surely don't understand it.

you might want to call your context "tenors" or something, but more
importantly you probably want to say \clef "treble_8".

...and you don't want to repeat \key ef \major, so get that out into a
global section that you define (earlier in the file) thus:

global = \notes { \key ef \major \time 2/2 } % and possibly more common stuff

You can reference that in your line above, like this

    \context Staff = bass { \clef bass \global }

(and likewise for the tenor staff)

Inside a global section, see above.

I'll go out on a limb here and suggest that it's an artefact of a
workaround of an old bug, but I wouldn't know.
