I can confirm from actual flying a model that sweep-back does add 'dihedral' effect.

I had a Pavel Bosak 20 powered Mig17 back in the 80's that had very little dihedral but the sweepback made her effective rudder / elevator machine.

If sweepback aids the turn ... then logic would say sweep forward would detract from the turn ... I know the couple of sweep forward wing models I have flown - I don't like ... which includes the 540 racer which has a forward taper wing ...
