Yes, I saw those, but unless I am mistaken, you didn't add a "U" after the 
second opamp, which would have returned the phase to the input's.

I see twice: once through the first op amp and again through the second one. 
The second one then outputs to the IF.

Anyway, to me, it is a very interesting and simple circuit.

I LIKE "simple". I am a great believer in the KISS principle.
