I have a zone 2-4 annual season ticket on my oyster card. I was going to Canning Town to Hoxton the other day. My journey is like this
Touched in at Canning Town and took the jubilee line to Stratford
Did not touch in the pink reader at Stratford (I'll explain why below)
From Stratford took the overground to Dalston Kingsland where I touched out.
Walked to Dalston Junction where I touched in.
Overground to Hoxton where I touched out.
I was charged the fare for travelling around zone 1. I called TFL and explained the situation and they refunded me and advised me to touch in the pink reader in Stratford in future.
I did not touch in the pink reader at Stratford because I thought by touching in at Dalston Kingsland my route (that I didn't travel via zone 1) became obvious. So I was surprised I got charged the via zone 1 fare as that will require an unbroken journey (e.g. travelling via Canada Water or via Central Line to somewhere central via Stratford or other convoluted route).
I still don't quite understand why I am required to touch in the pink reader at Stratford if I touch out at Dalston Kingsland?
Another question: Hypothetically speaking, if I were to start my journey from Stratford to Hoxton, do I still need to touch in the pink reader? The difference between this hypothetical journey and mine is that arguably this is the most straightforward route to Hoxton from Stratford, whereas you can argue Canning Town to Hoxton via Stratford is not the most straightforward route (but then I did touch out at Dalston Kingsland - didn't that make it "straightforward"??)
