[erlang-questions] In what order are pattern matching clauses evaluated?

While trying out Erlang, I noticed the following factorial function works:
fac(N) when N > 0 ->
N * fac(N-1);
fac(0) -> 1.
"Ah ha," I said, "the pattern matching is not strictly top-down." Is
there a resource somewhere that describes how the clauses may/will be
rearranged? Searching the archive, the closest thing I found was this
post, which says that the clauses will be grouped by type:
