Perhaps some reasoning why any supply name is allowed here?

I've asked for more information about power supply sequencing, I have
hopes I will be able to simplify all this. If I can't I'll expand the
description. The idea is that the power supply names are specific to
each sensor. I can try to specify them with conditional rules if that's
preferred.
