I would state it in stronger terms. Periodicity checking is always done on the z variable, regardless of the bailout condition. This applies to most of the inside/outside coloring options, also. The inside/outside options always use the z variable, except when the iteration count or a constant value is being used for the inside/outside coloring.
So for this particular formula, since it uses LastSqr (of a variable that isn't z) for its bailout, to be compatible with periodicity checking it needs to have the variables renamed so that the bailout condition uses LastSqr of z and not this other variable.
