Yes, I'd come to rely on the Back button with the old layout - but I didn't find it very pleasant to do so. It always felt like a workaround to me, rather than a navigation feature Amazon had consciously took into account when designing the layout.
Back does now what it always has: it jumps to the page, but does not restore the cursor position. No matter how you navigate to a given page, the cursor will always be on the 'default' hyperlinked item (usually the first hyperlink on the page).
Your suggestion that it should restore the cursor position if you use 'Back' to get there is quite reasonable, and if put to a vote, I'd vote for it. But you'd have to convince Amazon it is a bug, and they'd probably argue they were just being 'consistent'. This is one of a number of subtle navigational issues they could be addressing, but they seem to have other priorities.
