No, it's jarring for anyone using a mouse with scrollwheel as well. The motion ends up being very choppy. In fact, I'm convinced that this style of web page is designed by designers using apple touchpads (eg. MBP) who think everyone else uses them as well.
I agree that it's jarring and choppy with a scrollwheel. (I'm in no way condoning the design.)
You can file it under dark patterns, but I think it may be an accepted limitation - you have to consciously scroll in order to read the individual pseudo-slides. Overscroll? Go back til it's right. You can't just skim this 'presentation'. It's like a user has to 'pull' the information. And the variety of information types (as opposed to a typical webpage that may feature just one type of animation) keeps someone scrolling to 'see what's next'. The user is forever pushed to keep going 'just a little bit more'.
