I can do perfect or near-perfect dips with 50% of my bodyweight for 6-8 reps and my chest is by far my most underdeveloped and imbalanced bodypart
Now...I'm not saying that dips aren't the best because for all I know they are, but his little anecdote about bench press is not relevant. The reason there are a lot of bird chesters with a decent bench is because more people do bench. Very few people do dips, so the sample size is smaller.
The truth in chest as well as the truth in every other bodypart is that genetics are significantly more important than your exercise selection. I destroy my chest all the damn time and it just flat out does not grow the same way all of my other bodyparts do. (I'm talking proportionally. I'm pretty small everywhere, but I'm shapely and balanced elsewhere).
