Just going back a step, shouldn't it be worded something like

"The client MUST send a EHLO command after a successful TLS negotiation
if it wishes to start a mail transaction or use any SMTP extensions."

Because that's actually what we mean.

Also, saying 'or a command that does not require that a mail transaction
be open' means that you could use an SMTP extension which was advertised
before the STARTTLS, as long as it doesn't involve a mail transaction,
without resending EHLO.
