so say the disk fails on your main DB. or for some reason a customer needs data from 6 months ago, which is no longer in your local snapshots. In order to restore the data, you have to transfer the data for the full database back over.
With multiple databases, you only have to transfer a single database, not all of your data.
pg_dump has an option to output one-table-per-file. You can use this for selective restores later.
