i understand the difference between mutual inductance and leakage inductance

but i am glad you mention it

perhaps this frames my question better

would there be a negative impact having two counter wound coils on one pole from a mutual inductance point of view?

would the induction of one coil serve to fight the other coils induction?

i guess that is basically my question.

No, and no.  If the currents in the coils ran in opposite directions then the effects of the currents on the magnetic flux would cancel.  But that can never happen, as connecting the coils in series for the currents to oppose forces the currents to zero, as you pointed out.  Any other connection would mean that the coil currents run in opposite directions, which in turn would mean they act to change the magnetic flux in the same direction, but not necessarily by the same amount.  That's tantamount to saying each coil always exhibits its own inductance.
