Well, the Badd11 should be a B chord with an added 11th (4th); so you get:

B (1), D# (3), F# (5), E (11)

The Esus2(maj7) should be:

E (1), F# (2), B (5th), D# (maj7)

Given that both chords contain the same notes (but in different order), I can see why the chord finder showed the same chord; especially in BIAB, since [I believe] it doesn't really look at inversions, but at the notes that comprise the chord.
