Given that the chained hash will only allow access to keys found earlier in the chain -- ie. a key 'a' in a hash later in the chain will be hidden by a key 'a' in an earlier hash -- what is the advantage of a chained hash over composing a simple hash, from the chained hashes in reverse order?

I'm just wondering (but not dismissing) the use-case?
