Seeding is just one time operation that would allow you to restore VM from the backup file and then use it as a target for the replication job. This can be useful when you would like to replicate a VM over a slow WAN link.
Use backup files as a source for replication job is a different story. In this case VM data (new restore points) is retrieved from the new restore points of the backup job. The main benefit here is that you do not "touch" source VMs twice when running backup and replication job.

It means that your VM image in the target location is newer compared to what you're trying to use as a seed.
