Actually, according to those screenshots, they do. They've got 9 armour and 11 skill, while thureophoroi have 11 armour and 9 skill. In other words, frontal defense is the same but Keltohellinikoi have less protection from rear attacks while thureophoroi are more vulnerable to AP weapons.

Two of the extra armour points are for the thureophoroi's greaves (the Epeirote thureophoroi skin lacks these because it was originally used for a different unit), but I am not sure where the third point comes from.
