Specificity matters even in "general" training. If you want to be really good at squatting, you have to squat a lot. Even so, different rep ranges require specific practice. Someone who only does sets of 5 won't be good at doing heavy singles without practice.
In your example, obviously the guy with the same strength that trains the Jefferson deadlift will be better at it. Just like if the other guy trains overhead squats, he will be better at those. However, in this context, the idea is that developing the base physical adaptation, i.e. strength, will improve other endeavors. If one guy can pull 200lb max with a conventional deadlift, and trains Jefferson deadlifts on a regular basis, he will not be able to pull as much Jefferson-style, as the guy that can pull 500lb conventional that's never done a Jefferson in his life. That's the point. It's not that being stronger makes you good at everything - it doesn't, it's that it makes you better at everything.
Endurance training affects other endeavors as well, but not as generally as strength. Strength affects all activity involving force production, i.e. all activity, but endurance is more specific since the adaptations can affect the different energy systems differently (and even different parts of the body if we're talking about muscular endurance) and might not carry over as well from activity to activity.
One part I disagree with here is the notion that you train strength and the practice your sport. I think in some cases you would ideally train strength, and train conditioning, and practice your sport. If someone competes in MMA, do we say they are strong enough to compete in MMA by virtue of the fact that they compete in MMA? No, we say they should be stronger within the confines of their MMA practice. However, we say they are conditioned enough to compete in MMA since they compete in MMA. I find this inconsistent. Doing extra conditioning work, again, within the confines of their MMA-specific training, will improve their conditioning and allow them to express their MMA skill better.
We say all things being equal, the stronger fighter will win. Sure. However, what if all things are equal, and one fighter has the conditioning to last 7 rounds, while the other 5? If the fight goes to the max 5 rounds, the one with better conditioning will be fresher in the last round. Fights can be won with conditioning too.
