Max lateral force on an isolated tire is usually around 6 or 7 degrees of slip angle in most of the data I've seen. So the vehicle slip angle should be close to that on a car without rear wheel steering and without too much compliance steer. Although your source might not be using the term slip angle in the conventional sense.

I wouldn't exactly call slip angles less than 10 degrees (or within a few degrees of peak lateral) to be drifting.
