It's almost impossible to unintentionally mis-scramble a square-1 because if you get one move wrong, the rest of the scramble stops making sense. For the disqualified sq1 single, the scrambler probably made a mistake halfway through scrambling, and just said "screw it", and thus left the competitor with a easy scramble.
This doesn't happen with 3x3. The scrambler probably did one wrong move, but still did a full 25 move scramble.
True fact: 50% of why I don't do square-1 is because I usually get about 1/4 through a computer scramble and find that I've screwed it up. (the other 50% is I don't feel like learning the parity alg, but that's a different matter
