May confirm this behavior with Emacs 24.3.50.1. of 2013-07-06

Would call it focus-follows-scroll

I.e. if region-end is expected to be scrolled downward out of sight, cursor 
will remain at first line and thus expanding the region.

Would suggest a feature request, which would mean: no visible cursor displayed 
in this case.
