I'm still a bit confused with the article. It does mention that they are not using wastegates.
Excerpt:
Instead of a waste-gate, the motor will convert that excess energy into electricity by preventing the turbo from over-speeding.
I reason that they are using resistance on the electric motor to reduce the speed of the turbine. It makes more sense now. They can control the electric motor better than any wastegate by means of a computer. The resistance can then be immediately removed and boost would become available instantly because it would be spinning near the full-boost RPM (or island, as it is commonly called in the performance industry).

You've limited the turbine to max RPM and thus max boost. You only need to remove resistance or even reverse it and have the electric motor spin up the turbine when the RPMs drop below the boost value you want.
- bliti 13y agoYes, good point. Though I see this technology being used like KERS was used to preload the suspension and improve cornering. Mini boost spikes would be a possibility. In fact, an extra bit of power at the right moment can preload the suspension, too. I'm not saying they will cheat with it, but they will find a way to bend the rules a little bit. After all, you are only racing if you are cheating. :)
