Topic: Photoshop Save->PDF: hardwired to 72 dpi PDF?

I know this relates to Photoshop but the 'problem' is seen in the output PDF.
If I take screen shots and alter the res (no resampling) so I have the same image, same pixel dimension, but differing dpi and save each as PDF an interesting effect occurs.
A 72 dpi image at 100% zoom looks correct. With a 96 dpi image I have to zoom to 133% (note: 96/72 = 1.33) and to 417% with a 300 dpi image (300/72 = 4.17).
This implies the res of the PDF itself is hardwired in the PShop export to 72 dpi. This is equivalent to using distiller settins with the res on the 'general' prefs tab hardwired to 72 dpi.
It seems slightly odd given the apps are both high-end. Is this really the case or have I misunderstood something?
