Yes, that's what step 3 is saying. You can do whatever the SP supports,
assuming the browser is available. If not, then you don't have much choice
and if the SP doesn't support SOAP, you've got an "unsupported binding"
error.

Most of the profiles avoid any requirements about what bindings can be used
for request and response, unless the binding does (i.e. SOAP). I can do a
LogoutRequest via POST and get back a LogoutResponse via Artifact, then do a
second LogoutRequest via Redirect and get back a LogoutResponse via POST.
Would I? Probably not, but the profiles allow it.
