Stalling in a turn

I’ve been reading AFE PPL1 by Jeremy Pratt and in exercise 10b it says this:

“When turning there is an increased tendency for the wing to drop at the stall, but not in the way you might expect. In a balanced level turn, the higher (outer) wing has a higher angle of attack than the lower wing. Therefore the higher wing will reach the critical angle of attack first and stall, actually rolling the aircraft out of the turn.”

I thought that if you’re in a balanced level turn one would only be applying back pressure on the CC (the rudder and ailerons would be central). So how can the outer wing have a greater angle of attack? Surely it’s just higher off the ground than the lower wing.

I thought the lower wing would stall first as it would be going slower (less airspeed due to following a shorter track in the turn).

Jeremy or anyone else got an explanation?
