Apparently George Lucas doesn't know the plot of TFA. I guess the outline he hashed out was more of a 'collection of vague ideas' which Abrams may have discarded.
That's a very vague statement that people are building a mountain out of. From what he said it's entirely possible they're still using his story outline but he doesn't know how they've fleshed it out.
