No, absolutely not.  Modes are completely orthogonal to enabling and
disabling the regulator - modes reflect an efficiency/accuracy tradeoff
in the regulation, they are nothing to do with the regulator being
enabled.  Setting a mode should not affect the regulator enable state
and enabling the regulator should not affect the mode.

Yes, that seems to be the case.
