SC3's are definitely less sensitive to heat cycling than something like an RE71RS, Cup2 or Hoosier. Like Baddawg53 said, I wouldn't say they won't cycle out before they cord, but they they don't seem to fall off that hard.

I am running RE71RS's this year on a 2nd set of wheels, but I still have a set of SC3's on the stock wheels that have life and I am running them at some HPDE events until they cord (not going to throw away a good set of tires). These SC3's are on their 2nd season, 7 track days, 2 autocrosses, a little more than 1/2 worn and I haven't noticed them falling off in grip, as long as they are fully warmed up.

What I will say is that they do need a lot of heat in them to wake them up. The SC3's can be a little sketchy on a cold morning and because the car is a lot harder on the front tires, the fronts will come up to temperature before the rears and the car will get really loose in the rear for a couple of laps until the rears get hot. I went off in the grass at VIR at turn 4a/4b earlier this year on a cold morning because I didn't recognize that the rears were still cold. No damage or anything, got lucky.

You said this happened on the 2nd session. Did you go back out for later sessions that day and if so, how were the tires then?
