Watch the video first. Quote from the video link:

"Because I was in the ABS so much, the inner pads wore twice as fast as the outer pads and I only eyeballed the outer pad. BUT, what happened then is that the ABS system sensed the difference in braking between the R and L, then went into "dump mode" because it sensed I was on ice or oil. "Dump mode" causes a dump of all brake pressure in order to regain traction on ice. It was the dump mode that made a stupid mistake into a potentially deadly one. Google "dump mode" before you flame me."

Quotes taken from a Mazda message board:

"Happy to share my hard-won lesson. Following causes are of the necessary but not sufficient variety - in chronological order:
1. Inner brake pads wore at roughly twice the rate of the outer - I think because of the time spent in ABS during 3.5 track days.
2. I examined the outer pads (easier to see) and assumed pad wear was even - not!
3. I ran out of right inner pad material at speed in turn 2 - would have been dicey, even bad, but not catastrophic, given it only affected one of 2 independent circuits.
4. ABS system sensed uneven braking and executed "dump mode," which dumps pressure to regain traction on ice.
5. See video."

My observations:

1. Maybe MS needs to re-examine the MS3's ABS system
2. New drivers should be taught to check their brake pads more often
3. The club should be instructing its drivers to stay in their vehicles during a situation like this so that they don't get in the way of emergency personnel arriving on-scene. This in-car cam driver doesn't know if there's oil/coolant on the track, in which case another car could be following the same path very shortly.

Discuss.
