Yes, I believe so.  The condition that says thing A must be evaluated
before thing B is the presence of a sequence point between A and B.  And
it's explicit that an assignment operator (the = sign) does not create a
sequence point.  See the paragraph in that FAQ starting

    The second sentence can be quite difficult to understand. It turns out
    that it disallows code like
            a[i] = i++
    ...

for more discussion.  This is similar, I think.
