That's an illegal configuration. *If* you want a Ref > Pri > Sec config,
you need *minimum* three primaries. That's not negotiable.

Huh? Quite the opposite, the REF *must* point to *at least* one (better
all) primaries, otherwise the time on the REF will *never* go into sync.
Also, *all* three primary servers must point to each other *and* the
reference, otherwise time will go out of sync treewide should the REF
ever fail.
Back in the days of IPX, Timesync took care of all this fully
automatically, no matter what you configured (e.g the reference found
it's primaries automatically to vote with them). In the IP days, where
Timesync regularly can't find the setup on it's own, this is crucial.
But as a more general side-note: A reference > primary > secondary time
setup is virtualy never necessary, and unless there are very good
reasons, should be avoided. Use a simply single > secondary schema
instead, *especially* when you have an external timesource to sync with.

No. I think I know where you come from though. At one time, there was a
bug in Timesync, where that setup indeed wasn't working (a REF with an
external NTP source didn't properly participate in the voting with the
primaries). But as I said, that was a bug, and not a generally correct
setup, and in the meantime has been fixed.

Not my experience. At least not in an all IP tree.

Yes, I just restated it for completeness.
