Tom, characteristics not withstanding SE is not UL listed for underground use.
Unless you have some info that says otherwise.

Is THWN listed for use underground? If not then why do we use it in underground conduit. I believe that any conductor or cable that is suitable for use in wet locations is suitable for use in conduit outdoors. I fail to see how it makes any difference that the conduit may be partially, substantially or entirely underground. If we were talking about direct burial I could see a possibility of there being a problem.
