Yes it does (store ACLs both as a user_xattr AND an ext3 ACL at the same time).
It's designed that way. You might be getting away with the use cases you're
trying, but it won't work long term. If you want the underlying filesystem
to ignore ACLs you'll need to write a module that does this (and doesn't
pass down the ACL requests to the underlying file system).
