Yes, this is the danger when running bg fsck and your system
experiences a panic or other non-softupdates-safe source of filesystem
corruption.  As you discovered, the solution is to force a fsck to
repair all corruption and then proceed (optionally disabling bg fsck
permanently to prevent a recurrence ;-)
