This is *exactly* what I wrote/meant above.  :-)  If I were to
rephrase it in a longer form -- When you substitute A (for B), you
will be placing A in there (and in the process removing B) and
therefore it does not mean "you replace A".

We, non-native English speakers tend to use the word "substitute" when
we mean "replace".  To avoid confusion, it is probably best if the
word replace is used instead to substitute.
