Maybe, but if so it's a bad branding decision.
The problem is not only that the "improved user experience" looks too much like "deliberate crippling". It's also that they use the same name for the crippled version. They will be derided for that, and that bad PR is going to carry over to the entire Windows 7 brand. What are they thinking?
Apple put a Mac OS with a "different user experience" on the iPhone. But they didn't advertise that to anyone but developers. The word "Mac" is not mentioned in connection with the phone. The iPhone has a really different user experience -- it's not just the Mac OS on slow hardware with a one-app-at-once limitation, it's a whole different universe. And it is very deliberately branded, not as a very small, kind of slow portable computer with no keyboard, but as the world's best phone.
