Sorry, but I disagree with this completely.
Firstly, if he does his front squats first then his legs will already be fatigued for his cleans and this will affect the amount of power he can generate. Speed before strength.
Secondly, most oly lifters will start with a relatively narrow stance and will at least turn their toes out at the end of the second pull. This is the only way he will be able to sit down between his legs when dropping under the bar.
Just my tuppence worth.
