There is a great difference of "Could be" and "Will be".
Its better to speak actual happenings rather than theories!! The Jampacked train got RPF/TTE but stoppage at small station create loops of WL entry!!
As you alight Big Station sealed platform, its presumed you to be bonafide traveler (as Ticket-less travelers arn't allowed). With one or two check points, you just clear the rush, with thermal scanner check!!
