Yep, they all use the same formation.
However, shouldn't the Liby-Phoenicians be using the Iphkritean phalanx formation instead? From their description:
There were a huge number of these half-breed men, so the Carthaginians used them in the army. They were armed and armored much the same as their Greek enemies on Sicily. They were armored in a linen cuirass, Thracian helmets, and bronze greaves. They have the traditional round shield of the Greek hoplite, but use longer spears with the underhand thrust, much like the reformed hoplites of the Greek mainland.
