Sure there is- you will end up in both branches,
assuming that your information content defines "you".
If you go to sleep and wake up in branch A, that
doesn't mean that "you" ended up in branch A, because
sitting right next to you is a guy with a perfectly
legitimate claim to being you and waking up in branch
B! Both streams of consciousness exist, and just
because you happen to be in one shouldn't make the
others any less valid. There is a general rule here-
if a process is deterministic for one observer it must
be deterministic for all observers. Everyone has the
same laws of physics, after all. This reminds me of QM
debates about which slit the light "really" went
through- it went through both and that's the only way
to describe it that's consistent with experiment.
