So, you print for the step that arrives at the Crystall. It is NOT THE FIRST STEP INSIDE CRYSTALL! The step is inside World. The preStepPoint has fGeomBoundary because it so happens that is also started where the track entered World.

Same as above.

Yes, fGeomBoundary is where preStepPoint entered Crystall and since the step ends inside Crystall the postname == "Crystall" is also true.

Yes, so long as this is the first step inside Crystall.

Your logic prints for the step arriving at Crystall if it crossed another volume and for the first step inside Crystall in case the step ends inside the Crystall.
