Unless its mentioned explicitly in-game, sources external to the game have precedence, including the naming conventions, which came before SE identified Mide as a Hotgo.
Actually the information in Encyclopedia Eorzea can not be taken as "word of god." It is an intentional abridged version of FFXIV's setting bible with various parts obfuscated and other parts "translated" in order to intrigue fans with more info about the world.

Mide's tribe was likely determined before the HW expansion was released when they completed the outline of the Alexander story.
Which raises a interesting question, SE could have just given Mide a random tribe name, such as they did for Sidurgu. Why did they pick the Hotgo, a PC name option, and in SB, why did they pick the Dotharl - whom are connected to the Hotgo by being the instruments of the former's destruction.
The simple answer is that Mide was made a Hotgo due to them being a dispossessed tribe and the Dotharl were chosen for their deathseeker mentality which stands out among the other tribes.
