Not sure what is the case here. But I can say something: current electronics are getting ridiculously complicated in what power supply concerns. The project I'm working now, and the last I was, we had in a 4x4 inch board more than 10 voltages (1.0v 1.1v 1.3v 1.6v 3.3v 4v 5v 6v and I do not know what more) , all generated by micro controller configured power supply circuits. Those 10 voltages had to follow a very specific sequence, failing to follow it, could in worst case, damage the whole board. Basic explanation: if circuit part B is powered before part A, power flows "backwards" to A, melting it. In addition, an error in the configuration of the supply ASICs would also lead to too high voltages. That is, the output voltage was configured in one register. I think something along the lines is going on here.
