I am not Charles Atlas or Mark McGwire, but shouldn't you avoid going WAY past parallel on a squat?

“It’s so phenomenal," Carini said. "His hip strength — the size of his thighs — he’s taking these weights but he’s going way, way past parallel which means his hips are going way below his kneecap. And he’s just powering straight up. No hesitation. It’s just phenomenal.”
