In his recorded GSEM classes, Homer Kelley never referenced Clubface Lag, so we have no "official" authority as to its existence or non-existence.

Personally, I would classify the phenomenon you describe as Accumulator Lag. Specifically, the effort of the #3 Accumulator (Left Hand / Clubshaft Angle) to maintain its In Line condition (Left Arm and Club / Rhythm) during the rotational Overtaking process, i.e., the Overtaking of the Hands by the Clubhead during the Release Interval (Release to Follow-Through).

Thanks for the reply. So, the #3 Accumulator actually takes care of the clubhead and clubface simultaneously.
