If you read just a few lines further on:

"""
    If the EAP server is not resuming a previously established session,
    then it MUST include a TLS server_certificate handshake message, and
    a server_hello_done handshake message MUST be the last handshake
    message encapsulated in this EAP-Request packet.
"""

That is, a certificate is only "optional" if you're resuming an earlier 
session (which must itself have contained a certificate)
