I wouldn't have thought so, although it depends on the circumstances.  
Consider the following scenario:

1. I do something which causes the "location.hash" property to be set  
to "botttomPage", resulting in the browser bringing that region of  
the page into view;
2. I scroll the page back up, such that the "bottomPage" element is  
no longer in view;
3. I do something else which is supposed to take me to "bottomPage"  
as in step 1.

At step 3, "location.hash" would still have the value "bottomPage",  
so I wouldn't be taken there.

:-(

Regards,

Nick.
