I hear the 1st chord as being an Ealt.dominant (I usually associate tension chords w/dominates) and the 2nd chord as a Fmaj7/A, so to me this progression sounds like a cadance on the 4 chord w/the E7b13 chord being borrowed from the relative harmonic minor.
I'll have to reply to your other posts when I have more time to read thru them more carefully, your making me think to hard here.
