I think both the cases its not allowed, when you are debording in a station for which you are not having tickets to, it is considered as you are in the PF un-officially. So they can charge you. If you are booking a ticket from SBC-MAS with travelling/Reservation Upto station as PER(Note: not booking SBC-PER), then you can well travel with that ticket in Local train. Since in E-Ticket we cannot do it they might have said no problem in PRS Ticket.
