Do I understand correctly that your remark is about the internal variable 
'isearch-forward', and whether its value should change when using "fast 
forward/backward" searches?  If so, would that make a difference in 
practice?  IIUC it is changed by isearch-beginning-of-buffer and 
isearch-end-of-buffer.
