Well one thing can lead into the other over time. If you can lift 405 once, 315 for reps becomes pedestrian and 225 becomes boring. Lifting that much weight will turn you into a monster faster than if you had not pushed for that capacity. I've seen people who can treat a 225lb barbell as if it's unloaded and 100% of them look like dragon ball Z characters.
Body mechanics, leverage, and neuro-muscular connection definitely come into play. I could deadlift 430lbs for reps at my peak, and I while I was no string bean, I also didn't look all that muscular compared to the other lifters at my gym. I have ridiculously long arms relative to my height and relatively shorter legs, which gives me an advantage for deadlift. I had monstrous-looking guys watch me lift and then ask me what stack I was on. They didn't believe me when I said I was natural.

Again, not relevant.
