If two species form a hybrid, with certain characteristics, and then in a
completely different locale, the same two species independently form a hybrid,
with different characteristics, are the two different hybrid forms the same
species?

By definition, all hybrids between two species belong to the same
nothospecies (hybrid). However if speciation by hybridisation is added
to the mix, then it becomes a matter for determination by observation
(and argument over species definitions).
