Good point. In my case it may well have been, as I was editing shelves, and I seem to remember finding that it wouldn't work properly unless I removed the original books from the Glo before adding them back with altered shelf info.
But whatever triggers this behaviour, it seems that everyone agrees that it is undesirable to have the current read booted off the Home screen.
