Why not just open the WSDL in my IDE?

Because you're on a call and need the operation name, its message-exchange pattern, and the SOAP action in ten seconds. This gives you the shape of the service without a project import.

What does 'one-way' or 'request-response' mean here?

It's the message-exchange pattern, interpreted from the operation's input/output declarations — one-way means fire-and-forget with no response message defined.
