Section 5.3.3 says:

Example of use of the MODE READER command on a mode-switching server:

    [C] CAPABILITIES
    [S] 101 Capability list:
    [S] VERSION 2
    [S] IHAVE
    [S] MODE-READER
    [S] .
    [C] MODE READER
    [S] 200 Reader mode, posting permitted
    [C] CAPABILITIES
    [S] 101 Capability list:
    [S] VERSION 2
    [S] READER
    [S] NEWNEWS
    [S] LIST ACTIVE NEWSGROUPS
    [S] STARTTLS
    [S] .

In this case, the server offers (but does not require) TLS privacy in
its reading mode but not in its transit mode.

It should say:

Example of use of the MODE READER command on a mode-switching server:

  [C] CAPABILITIES
  [S] 101 Capability list:

  [S] IHAVE
  [S] MODE-READER

  [S] 101 Capability list:
  [S] VERSION 2
  [S] READER
  [S] NEWNEWS
  [S] LIST ACTIVE NEWSGROUPS
  [S] STARTTLS
  [S] .

In this case, the server offers (but does not require) TLS privacy in
its reading mode but not in its transit mode.  Despite the 200
response code, the POST capability is not advertised, indicating that
the POST command is not yet available but may become available later
(presumably after a TLS negotiation and possibly authentication).
This example shows a case where the 200 response code cannot be as
accurate or fine-grained as the CAPABILITIES response.

Notes:

This precision should be added because of the comment "Reader mode, posting permitted". It makes it clearer and incidentally provides an interesting example regarding the use of the 200 response code.
