Exactly. That is what I thought too.
Shorter lenses have greater DOF and because you are using shorter lenses to get the same AOV as with 35mm you are therefore getting more DOF.

Makes no sense, for same AOV you are using shorter lenses and have a smaller reproduction ratio with APS size formatvs FF 35mm. DOF should not be same as 35mm full frame format. It should be more DOF than 35mm. JCO

You correct Don. DOF is an issue for 1.5x cropped APS digital sensor cameras. Of course, having said that its only an issue if you enjoy a shallow DOF. For those who want greater DOF I guess digital is a godsend. Personally I like the DOF of my current film setup, so a full
frame digital camera with no crop would be just the ticket.
DOF on the *ist D is more or less the same as film i.e. I'm still often struggling to achieve a decent DOF only the cropped AOV is an issue for me.
