yes, very possible. I see this with our sites – and I’m only ever looking in the first five pages.
Quite often they will be list one immediately after the other as well – almost as if the second page “piggybacks” on the higher rank of the first listed page.
EDIT :
However, I have assumed that you are talknig about different pages on the same domain – in rereading your post – I’m not sure thats what you are seeing?
