No. set Px, Py simply sets the Px register to point to the same PMC
as Py already points to; it does not care about the content of the 
PMC in any way. The future 'assign Px, Py' will call a vtable function 
(set_pmc); however, in the quoted example, the pure register level
behaviour is all that is intended.
