System generators are not transferred in backup, they're recreated from
scratch when a database is being created during restore. And you cannot
explicitly issue either GEN_ID or NEXT VALUE for them, the engine itself
increments them at the low level, without looking at
RDB$GENERATOR_INCREMENT.

So I believe it's absolutely OK, although possibly looking weird.
