Sure it does. As long as the destination QEMU CPUs have not been
started, you can fallback by simply killing the dest QEMU and
restarting CPUs on the src QEMU.
FWIW, I did a test and disabled the starting of the CPUs on the
destination side and
did a sleep() instead. Before the sleep() was over the Qemu on the
source side had already disappeared.
