Yes, it appeared to be in a hard left hand skidding turn, and actually appeared to be flying almost sideways. It ultimately snap rolled to the left, going almost inverted prior to impact. As compressor stall pointed out above it could certainly be related to a Vmca (Vmc in U.S.) loss of control incident, and as far as my limited knowledge extends on this, the only way out at low altitude is to reduce the power on the good engine. That of course, requires nerves of steel.
I seem to remember a video from 3 or 4 years ago of some guys showing off in a King Air, I believe in Central or South America. Anyway, they were doing low level skidding turns near the airport and the video caught the exact same sort of abrupt violent snap roll as shown in the video of the Addison, Texas accident.
