Same wattage (40 Spray) but the mouth of the pulmonary veins should not 
be mistaken for just the burn - more importantly the common ostial 
origin needs to be burnt.
The picture labeled dual orifice represents two separate orifices.
The picture labeled common pulmonary vein orifice shows a common 
pulmonary vein orifice stretched open (There are actually two orifices 
within it and the sucker has gone into one)whereas it looks like common 
pulmonaryvein2 when unstretched.Burning within this just the individual 
ostia would leave a left atrial trigger within the common pulmonary vein 
area.
