No, the option means just that the next job of the fileset is not going to be
forced to full. The effect of exclusion etc. is still there though.

I don't think VirtualFull backup uses fileset to see which files to check and
which not to - I guess it just merges multiple backups. I'm not sure though.
But if a file has been marked as deleted by an accurate incremental backup, it
won't be included in VirtualFull.
