Question re double stop in Cross Tuning AEAE

I'm trying to learn Lonesome Road Blues in A cross tuning by ear and trying to determine if the open cross tuned E string (lower E) works with the B note on the A string?

It sounds like that is the double stop being played. But it feels counter intuitive, possibly because playing in cross tuning is new to me? Anyway I'm unable to determine with certainty by ear if that is actually being played. E + B notes ???? I can't remember ever playing the two as a double stop in standard tuning.
