Unfortunately, this is not correct.

The unbundle command can also be rolled back, as can import, as can an
incoming push.  Having a proliferation of command names with "un-"
prefixes is not helpful.

"rollback" is a better name.  A few doc comments that describe which
commands can actually be rolled back, so that this can be seen when
doing "hg help rollback", would then make all the difference.
