Yes, exactly this way.

If a PDF workflow is used or an image is directly sent to CUPS there is 
no PostScript data stream involved. In these cases the pdftoraster and 
imagetoraster filters parse the PostScript code in the PPD file via a 
CUPS library function and so alo in this case both the paper size in 
numbers and the paper size name get made use of.
