Could be, I read the same thing. Though oil cooled makes more sense to me.
Turbos run extremely hot, Oil would be able to withstand higher temps then water.

You don't want to get water vapor in the engine cooling system and turbos run at 300+ deg. Celsius, so for them 2 b water cooled the ///M5 should have a separate pressurized water cooling system on the turbos to eliminate any bubbles forming.

Anybody?
