LVC/LVA for a 1 Cell LiPo?

If the LiPo and Device positives are connected to the same pad, the LiPo will directly power the Device without passing through the Protection circuitry.

Not if the grounds are seperate, which they are. Normally, you see circuit interruption in the + lead, but there is nothing wrong with switching the ground lead. In fact, that's how old-style dome lights are switched on via pin switches in older cars. Car horns operate in a similar way. Just depends on the application. Could just be a matter of the circuit using an NPN vs a PNP transistor to do the switch action...

Okay, do you see the labeling though Brian? If you ignore the drawing they provide, doesn't it look like they are switching the + batt terminal?
