You've got to scope the forms so it can find both. Something like:
.sign-in-form
= form_for(:session, :url => sessions_path) do |f|
...
.sign-up-form
= form_for(@user) do |f|
Now the spec can be more specific:
rendered.should have_selector(".sign-in-form form",
....
rendered.should have_selector(".sign-up-form form",
....
