It is not.  Strictly speaking, setpagedevice (and any code that  
redefines that operator) is discouraged in DSC-conforming documents.   
Use of setpagedevice has to be limited to code surrounded by %%Begin/

Some day I'm going to have cupstestdsc updated so that it can detect  
this sort of problem... :)
