Nope that is not true in the general sense, which can be demonstrated simply by running: 

open FOO, ">x";
$foo = <>;

in one window and then in another: 
[jonathan@orpheus test]$ /sbin/fuser -u x
x:                    5665(jonathan)
[jonathan@orpheus test]$ mv x x1
[jonathan@orpheus test]$ /sbin/fuser -u x1
x1:                   5665(jonathan)

However it is true for most Windows applications.
