Power is proportional to switching frequency and to the square of the supply voltage. Reducing the supply voltage is the main vehicle to reduce power consumption, but with standard CMOS you run into the problem that transistors leak a little current when they're run at or near the threshold voltage because they don't turn off completely (you need significantly more than the threshold voltage for that.)
So in a totem pole circuit (used in standard CMOS) current leaks straight from Vcc to ground - not good. They must have designed some tricky circuits that avoid this current path although the transistors are still conducting a little.
Of course the real reason behind this is that even standard CMOS designs suffer from leakage -- the smaller the more leakage -- so they can apply these techniques to standard designs as well. That will probably be a necessity at some point beyond 22nm.

That sounds reasonable given how they were begging for donations "to defend themselves" against the leak.
Although calling "being afraid of getting outed as a donor to a right wing money laundering organization" "repositioning" is a bit generous.
If I was one of the donors I'd run like hell since they can't keep highly sensitive information under wraps.
