Wherever you claim that (in the absence of a penalty fare) PAYG users
can get by with paying the minimum possible fare instead of the correct
fare for their journey, so can paper ticket users. And, for that

to this additional degree of scrutiny.

Somebody traveling on a paper ticket or Travelcard from an ungated
station to a Z1 station can get by with a Z1 ticket, even if his ungated
station of origin is in Z6, unless he's caught outside his zones.

The caught outside his zones bit is the key. A paper ticket user
that gets on in zone 1 with a zone 1 only ticket going to an ungated
zone 4 station might get caught by an inspection. A pre-pay user
will be okay if they get stopped and if they don't could "forget"
to touch out to save themselves some money.
