Yes, it can. I did Diamond/Passion many times and so did other people it gave Passion or Diamond, most common outcome was Passion. (of course I was one of the ones that only got Passion from the combo >_<)

Both of you must be on Android and that is why it is showing up in the Valentine's addition but it doesn't change the fact that it's a bug.

Yes it does act like a mirror. Myself, King, a few neighbors, and many people on the TL forum tried breeding with Passion and this has been the conclusion. It either gives Passion or a Dragon containing colors from only the other dragon. Passion gives nothing to the combo.
