Erin, you and I have discussed this previously, when during The Perks of Inception, Erin attempted to block the Haki infused spheres Ralph had created. My explanation to you then remains unchanged, and what Su is saying here is exactly what I told you back then.

Yes it is possible for a Logia user to utilize elements that are already preexisting in the environment. The mother wiki describes as follows: "They can accomplish so by utilizing their own element from their own body and adding it to the preexisting source, augmenting their already powerful force to higher and more versatile levels.

In order for a logia user to manipulate their preexisting element (in this case, the wind) Erin would have to essentially merge with it, meaning it is exactly as Su states it to be: it would still be apart of his body.

So just so we're perfectly clear on this, that wind does in fact become an extension of Erin's body itself if he merges with it. Which again is why it isn't wise for a Logia user to expend their element over a large radius against a proficient Haki user, like Smoker did against Vergo (though granted, as we all know, Smoker was doing it to nab Law's heart). Furthermore, this is why Crocodile had no issue using the surrounding desert against Luffy.
