Coil tapping and coil splitting each nap have their advantages and disadvantages. I wouldn't call either better, just different. Tapping doesn't reintroduce singlecoil hum, though.
As to why the SHS Phoenix-nice axe, BTW- has 2 push/pulls, I honestly don't know. These guys might know more.

You might also contact the guys at the reborn Electra guitar company. They're industry vets, and they bought the Electra IP along with the brand name when they revived the company a few years ago. They may even have the schematics in their desks right now...
