No, it doesn't. The values of global variables are still cleared when
only the names should.

Here's the result of a slightly modified foo.m (attached) on R2013a.
Indented lines are echoed commands, the others are input/output.

>> dofoo
    foo  % Call the function
X IS NOT INITIALIZED
    foo  % Call the function
CALLED FOO
    foo = 1;  % Assign to a variable
    foo  % Refer to the variable
foo = 1
    clear foo  % Clear the variable
    foo  % Call the function
CALLED FOO
    clear foo  % Clear the function
    foo  % Call the function
X IS NOT INITIALIZED

By the way, what I said may not have been consistent. I'll try to
clarify another time.
