You bet it does... moderate sideslip towards the live engine is never a bad thing and on some older types it was absolutely necessary to maintain directional control at low speed. As AAIB noted in report on British Airtours B707 crash at Prestwick in 1977, aeroplane's certified Vmca with 5° bank was 119 kt but when bank was reduced to zero, Vmca jumped to 160 kt.
On single aisle Airbus I never gave much thought to how much slip is needed; as soon as engine failure was detected, skypointer index on AH turns blue, indicating it's representing single engine sideslip target. One just centered it and had optimal sideslip.
