The thing I took away from that, is AKIRA came out in 1988. So by the Late 90's - Early 00's, you had future animators from North America, who were in Anime clubs with anime still being a 'niche' during High School, but then getting jobs, and using that one scene in Disney/Nick/Dreamworks/Etc works.
It just shows how AKIRA, while still being a timeless classic, is no longer a timeless classic of a niche but rather a large, larger portion of animation that is respected and has a foothold in pop culture. Just like how South Korea is starting to make inroads with it's pop culture.
