Perhaps it's a form of copy protection but IMO, without it being digital, DRM isn't possible.

I did purchase this book because the last version has so many good reviews and I too would have preferred a digital copy but to me, calling it DRM is technically incorrect and smells like bait. I'm mostly disappointed that I fell for it.

This discussion hinges on some pretty fundamental questions of what is "a book," whether you can protect digital rights by not having a digital form, and whether the term DRM is understood to mean any kind of IP protection. I think there are reasonable answers to all of those that would have people falling on both sides of the question.

If physical only was done to prevent piracy, it is at the least a "RM" move.
