But it doesn't, necessarily. They are different things entirely. Let's try a thought experiment: Imagine a world where Grimoire is only awarded for Crucible kills, one per kill, and max Grimoire is 200. Dude A gets max in 5 matches, but then goes on to other activities because he's bored. Dude B gets max in 50 matches. Dude B actually has more experience. But not, I would argue, skill. Experience and skill are different. Skill is mechanics. Experience is knowing how to use those mechanics. But the variables are independent.
