In most cases this is probably better, but sometimes there is no logical filter that works on you hvae to rely on sort order. One example might be a gallery, I might decide to look though pages 1-10 tonight, 20-30 tomorrow, etc. An arbitrary primary key is the only discriminator that makes sense here. Another example would be classical forum posts, they are sorted by last active but sometimes I'll want to jump to page 134 because that's where I got up to last time and bookmarked my place. That said, if users were doing this in my software I'd definitely be looking at how I can improve their workflow.
