I've not spent much attention to the combination of alternative
conformations and NCS restraints. The reason is that alt. conf. are
useful if you have high resolution, and NCS if you have low
resolution. If your resolution is sufficiently high to support
alt. conf., I figured it should be OK to refine without NCS restraints.
