[SEL] rear tool post...deviates!!!!

Peter,
I'm not asking about the force direction. I can see that parting on the 
backside can be used to pull the headstock shaft downwards.(Incidentally 
this lifts up on the carriage and it likely an even worse situation)
But my question was, what is the issue on pushing up on the headstock 
when parting? It is the same reaction as you get with standard turning.
