Yes, I mean this.

I think it doesn't say this splitting _before_ assignments is only true
when (A) is used. Looks like if (A) wasn't used, splitting will _after_
the assignments:

    % print -l ${=xx::=foo   bar} . $xx . ${(A)=xx::=foo   bar} . $xx
    foo
    bar
    .
    foo   bar
    .
    foo
    bar
    .
    foo
    bar

So I think maybe it should say this splitting before assignments is only
true when (A) is used. The original statements give me the feeling that
this splitting before assignments is peformed in any conditions. Or I am
misunderstanding the statements?

Thanks.
