At least
I noticed at 6:10 and 1:02:30 they both made a similar mistake on the break shot. The seemed to be guessing on their break shots sometimes and would benefit from a lesson or two with Ray Martin or Mike Sigel.
Poolmanis in his second video showed how to avoid that.
break at 6:10 is little bit trickier than first glance shows. I did measure angles from pic and im pretty sure he got 20-22 degree cut on break shot. That means about 5-7mm thicker than half ball hit. If he had half ball cut or more he would float further up to rack with less speed and then he probably could not scratch..
Tangent line seem to hit front ball close to full in face. So half ball hit to first corner ball to upside of ball with stun(or possible slight draw on cueball) could scratch both side pockets if unlucky.
If he wants to cueball slide to rack with high to avoid scratch, he should shoot it hard speed. Those pockets seem to play tough on high speed so he chooses more like slow roll it.
I think it is best because pocketing ball is harder than normal on that one.
He just did shoot it too hard to hit higher on rack and cueball hit rack couple times and scratch on that is about 75%. He should shoot that almost as slow as possible with quite a lot outside english to have high chance to avoid that. Outside english on that break shot with follow makes cueball hook little steeper (after hit to rack) towards end rail than just follow, often meaning not scratch vs scratch.
In other hand he probably then have just couple balls of from break. One ball from rack should be close to end rail with cueball to continue run still..
