Perhaps, but this is probably due to my poor expressive skills. Here we go again:

Gaesatae can be
1) A tribe
2) A type of elite soldier (EB meaning)
3) An actual instance of (2) (Tindanotae are an instance of Gaesatae, as are Gaesatae - if you find it confusing: a home may be a buidling, a house may be a home and a house may be a building. It doesn't mean that all houses are homes nor that all homes are houses, though!)

And I have sinned against clarity by using multiple meanings of the Gaesatae whithout warning I did.

Now here's the message rephrased:

"No those are a Galatian version of Gaesatae called the Tindonatae units, who unlike the Gaesatae which form the Gaesatae units weren't picky about who employed them."
