Rigid Tapping, How to work with rigid tapping & TRAORI

The Sinumerik 840D documentation gives explanation on rigid tapping G331 & G332 stating that the LEAD is in Z direction.
The documentation explains nothing on how to use this under TRAORI.

How does this work when TRAORI is active and tool is not oriented to the MCS Z-axis?
The machines I want to use this on are Starrag machines with Rotating table/Tilting tool & Rotating table/Tilting table.
We do all machining with TRAORI.

Thnx
