My Cambridge to Underground Zones 1 & 2 tickets don't get eaten at East
Putney which is much more baffling.

It's eminently logical actually. The ticket has two validities - one LU
and one NR. A LU gate only looks at the LU bit. It cannot know whether
you have had your ride on NR before entering LU or if the NR trip is
after leaving LU. Therefore the gate has to give you the benefit of the
doubt and return the ticket once it has done what it needs to do in
respect of the LU validity. Simple.
