Question about VoiceOver focus when moving between pages in Safari on OS X

Hi.
I'm new to mac, and I have a question on Safari.
When I press Cmd+[ to go to the previous page on Safari, I find that the VoiceOver cursor always jumps to the top of the page, not the element where I left. Is there any ways to change this behavior? It seems that in iOS that's not the case.
Thanks in advance.
