How to encode table movements in DICOM Structured Dose Reports

Hi DICOM experts,
I would like to correctly encode the table movements during FLUORO in the DICOM Dose Report. In TID 10003C (Irradiation Event X-Ray Mechanical Data) under DCID 10008 "Dose Related Distance Measurements" there are these two possibilities:
"Table Longitudinal Position" (Code Value 113751) and "Table Longitudinal End Position" (Code Value 113759).
It is defined like this:
"Table Longitudinal Position with respect to an arbitrary chosen reference by the equipment. Table motion towards LAO is positive assuming that the patient is positioned supine and its head is in normal position."
So unfortunately the position values are dependent on how the patient lies on the table. However for changing the "longitudinal" position I would have expected that the motion is described towards heat/feet and not LAO position.
Is this just mixed up with the decription for "Table Lateral Position" or do I misunderstand it completely wrong?
