Yes. dub_hash is a hash. {$name} accesses an element in the hash, creating it if it didn't exist already.

{$name}{$uid} is shorthand for {$name}->{$uid} which implies the value accessed by $name is a hash reference. Again the hash element is generated if it didn't exist already.

 = {...}; is an annonymous hash whose reference is assigned to the element accessed by {$name}{$uid}.

The result is a HoHoH - hash of hash of hash.
