To keep most aircraft in a turn you have to hold a small amount of aileron - if
you centralise the yoke the aircraft will tend to roll back to wings level. The
angle of attack is significantly different as you roll into or out of a turn
because the wings are moving up or down relative to the free stream and that
will tend to oppose the roll but that effect is the same whether you have
dihedral or not.
I've never flown an aeroplane which behaves like that. The latter part of the statement refers to aerodynamic roll damping.
If you have no idea what my diagram is showing then perhaps I'll leave it at that. All my students understood it perfectly well.
Both BOAC and I have given the answer.
