Presumably, he meant that @array identifies the entire array, while $array[0] identifies the first element of the array, thus "changing" the @ to a $ to access a single element. The mnemonic device is not "@ for array, $ for scalar", but rather: $ is for single elements, be they single elments of arrays or hashes, or actual scalar variables. @ is for lists of data, whether entire arrays, slices of arrays, or slices of hashes % is for an entire hash.
