Alan mentioned in another recent thread that all tickets for a given (physical) train are stuffed in a single envelope, which is scanned in a single batch, and then a single train number is assigned to the entire batch.
The conductors won't separate out the tickets for 7, 27, and 807, so they'll definitely all be in a single envelope and scanned as a single batch (as train 7, most likely, regardless of which train your ticket was actually for).
As such, I doubt you would see more than one credit show up.
