From the document:
These third-party identity providers were tested for interoperability with Microsoft cloud services using WS-Federation and WS-Trust protocols only. Testing did not include using the SAML protocol
That doesn't imply that WS-Fed is required, but that they didn't document any SAML providers. Both ADFS and Azure ACS support SAML 2.0.
