I have also gotten expired link errors, too, and it's kind of jarring. I don't know of any other site that does its paging in this way, and I'm not sure of the advantage of doing it this way. All I experience is a reading session that can't be left alone for some arbitrary amount of time lest I lose my place.

It's also been like this for years, so presumably PG doesn't care enough about the usability to change it.
This type of thread comes up every month or two, someone explains how/why it happens and then we go back to having the same, broken interface. I doubt it will ever be fixed.
