It does, which is why you would leave the existing VP in place, and
wire around its PPS signal. The Z3801A would then have no knowledge
that the PPS wasn't coming from the VP, assuming the VP was indicating
valid PPS (otherwise the Z3801A would go into holdover).

Conceivably, anything with an output similar to the VP (0-5 V, sync on
rising edge, 200 ms pulse) could.

That's the real question to be answered.
