Yes.

Swift has one port with two different APIs: AWS S3 compaible one and
OpenStack one.

So it needs two different authentication capabilities;
authtoken is one middleware for OpenStack API and s3token is the other for
S3 API.
If there are multiple authentication middleware, the primary shouldn't
reject requests without legal credentials because the second may accept
them. So s3token (and ec2token) have to come before authtoken and to be
used with authtoken because it doesn't reject non-S3 requests.

In other words, s3token is just a converter from S3 credentials to
OpenStack tokens.
