Phalangitai deuteroi vs. pantodapoi phalangitai

[Sakkura]

Western Hellenics have phalangitai deuteroi, eastern have pantodapoi phalangitai/machimoi phalangitai. They are almost identical, but I saw something that seemed a little weird.
In the description of pantodapoi phalangitai, it says how they are "prone to rebellion and discontent, and hence are more expensive than their Makedonian contemporaries". Despite this, pantodapoi phalangitai (and machimoi phalangitai) cost 321 mnai per turn while the phalangitai deuteroi cost 350 mnai per turn.

The stats of the units are almost identical. Pantodapoi phalangitai has one less officer than the 2 other types, while phalangitai deuteroi has a different secondary weapon than the other two types - a sword with higher attack but lower lethality and not armor piercing.

So, uhm, the price difference seems quite weird, especially when it is the reverse of what the description says.
