I regognized the same!
One afterburner is missing just after the minimum speed pass
I have a photo on which you can see the "normal" smoke on the left engine and the afterburner on the right engine a few minutes later you only see the right after burner for the rest of the program (saturday only, friday 19th both were on)
erm here:
Perhaps one of you guys have a better pic on which you can see the heat blur, I wonder if this pilot (Ruet IIRC)indeed finished this display with just one engine workin?
