Key Influencer Visual - question about comparing proportions

Hello  -  Would appreciate some help in understanding this visual.     I understand the "absolute" mode, as this is seems a bit more obvious.  

What I don't understand about this mode, below, is how it compares proportions.   Proportionately, it seems that the value I am comparing against the total should be smaller, not bigger.    In other words, the blue value on the right shows a total of 12 won opportunities....the comparative value for the whole is 78 (grey area).     Why are the proportions of the lower value (in blue) so much bigger?
