The array references in @AoA are to four distinct locations, so they are all unique, even though their contents may be equal.

We've shown you a bunch of ways to get uniqueness, mostly having to do with hash keys. You can form a suitable key from one of these array references with join ',', @{$AoA[$idx]}.
