Having it this way gives synergy between the 2 talent trees. Both Benediction and Judgements of the Pure are beneficial to both specs but might not be the over all choice for the Paladin that chooses the spec when he compares the talent next to both of them (ie Imp Bom and Spiritual focus). This also makes both talents competitive when looking at all 4 talents. As holy a player that wants to spec shockadin they might question having a imp Bom to get a bit more ap for the conversion of in sheath of light that is a bonus for them because the bonus from sheath of light being a Hot is what they are after. For Ret it might question if the Paladin wants to have more of a chance at fighting push back for his healing spells assuring that he can heal if he needs too. Even though he wouldn't be able to do it very long or have a whole lot of mana it still gives the choice to the player giving them 4 viable talents to choose from.
Even though i do like your idea logically i don't see them changes Benediction to give a coefficient that would over all better some aspect in Ret and to be truthful imo i don't think one would be needed.
