Points/condenser with a single input dual output coil

[MitchMan]

I've done some searching around and saw people say that when running points with a single coil you don't need to wire both condensers, just one and forget the other.

So bassicaly wire both points leads to a single condenser and then wire that to the coil, I'm using a Harley single input/dual output 3ohm coil. Just wondering why only use one condenser and is there any harm in wiring in both condensers.
