I guess it's not a bug, but a carry-over of what was a reasonable design decision on an early Palm with limited memory, but is no longer a reasonable design decision.
On a limited memory device there is going to be a choice between limited memory one will have a trade-off between slow paging, at least in reverse, and unpredictable reverse paging. In Plucker, the issue was solved differently, at the cost of slow paging both forwards and backwards in documents with large paragraphs and some additional memory use.
On a modern device with oodles of RAM (all Kindles have oodles of RAM by the standards of early Palms), this is a poor design decision. One wants to be able to find the exact place one was reading more easily when one jumps to a footnote or forward and then comes back.
