'Basics tutorial' issue

[FrankAtHexagon]

In the Defining the service section, there's this text:

Once the client has finished writing the messages, it waits for the server to read them all and return its response.

However, in the Client streaming RPC section from the Core Concepts documentation, it says this:

The server responds with a single message (along with its status details and optional trailing metadata), typically but not necessarily after it has received all the client’s messages.

Both statements cannot be correct.
