Refget Sequences returning subsequences and choice of 200 vs 206 status code

The “[Method: get sequence by ID](https://ga4gh.github.io/refget/sequences/#method-get-sequence-by-id)” section says

> If a sub-sequence is requested via a Range header, the response must be one of 206 and only contain the specified sub-sequence, **be 200 and contain the entire sequence** (thus ignoring the Range header), or 303 redirecting the client to where it can retrieve the sequence.
>
> If a sub-sequence is requested, the response **must only contain the specified sub-sequence**.

The first sentence's 200 response option and the second sentence are not consistent with each other.

The **Response** subsection of the same section says

> On success and either a whole sequence or sub-sequence is returned the server MUST issue a 200 status code if the entire sequence is returned. A server SHOULD return a 206 status code if a Range header was specified and the request was successful.

The first sentence is mostly incomprehensible. I _think_ what it's trying to say is

> When a successful request results in the entire sequence being returned, the server MUST return it with a 200 status code regardless of whether the request was for the whole sequence or a sub-sequence that covers the entire sequence.

However that is not obviously the best approach and it is not very consistent with the second sentence.
