I listened to it, and my first reaction is mixed. I can recognize the tune because of the first 5+5 notes, which are lower, while it becomes much less clear thereafter. Even so, while I can tell different pitches apart, the intervals do not "sound right", and I'd say that the rhythm has a role in this recognition. I also noted that the frequency I hear less is not the highest, but the second-highest of the melody. That seems strange to me. Altogether, my feeling are that this example confirms what was already said: you can somehow distinguish different frequencies, but perception of the intervals is altered.
