So there is exactly one dirty-bitmap that get's nulled after a backup?

I'm asking because I have Backup setups with 2 Backup Servers at
different Locations, backing up (file-level, incremental) on odd days
to server1 on even days to server2. 

Such a setup wouldn't work with the block level incremental backup and
the dirty-bitmap for pve vms + pbs, right?
