The difference is one level of indirection. In the first case, you have an array containing arrayrefs pointing to arrays containing strings. In the second case, you have an array containing a single element, which is an arrayref pointing to an array containing arrayrefs pointing to arrays containing strings.

If you backwhack your first array, you'll get the same results as using the second array directly.
