Indeed, with that understanding there is no contradiction.  But what 
"autoselection [...] never unselects the minibuffer if it is active" means 
in practice is that autoselection is disabled while the minibuffer is 
active.  If you M-x, move the mouse to another window, type a command and 
RET, no autoselection happens.  I'm not sure that the complexity of what 
you suggest is worth the price for this specific case (ESC x instead of 
M-x), given what the behavior is with M-x.
