Generally your squat looks fine, but I wouldn’t force yourself to break at the knees. People squat differently and people’s bodies work different. I would bet you can get some extra ROM (and squat more weight more safely) by letting your knees and hips break at their natural timing, rather than forcing it. Play with your stance width to get to where you’re strongest.
Also, if you can describe a person as “some bro”, you should probably not take advice from said person.
This is kinda goofy of him to say. Yes, a lot of people over-emphasize breaking at the hips, but forcing a break at the knees first isn’t exactly sound advice either.
Slight detour for a parable here that will explain why I hate one-size-fits-all form nazism. I had a baseball coach in high school that forced everyone to throw exactly like him. He had pitchers that could touch 80 MPH with good control and good off-speed pitches at 15 years old, then would blow up and rebuild their pitching mechanics in his image. We all got worse and most of us have permanent damage to our throwing elbow or shoulder from it.
Bottom line: you gotta figure out what works for you. Over-arching principles hold true, but forcing your lifting form to look like someone else’s isn’t the right way to go.
