Alex,

1. First surface is the front surface. Second surface is the back surface. A plane of glass delivers two reflections as a result.

2. The surfaces reflect in parallel but the angle is shifted a bit on the back surface reflection.

3. I am pretty sure the original Bris is coated but not with mercury as a traditional mirror.
