i got mine approved in hcmc and then my dependants in Taipei. Taipei was a little funny, they asked why I didn't apply for the dependants in hcmc and they wanted to contact the hcmc embassy. Luckily (or not), hcmc didn't reply to them so Taipei just approved my applications after my interview when I told them I had to fly home the next day.
So, no I don't think you have to apply for the dependants at the same embassy as you since there is no official document saying so. However, it depends on the person who's looking at your file and how their day is going. Just make sure to apply outside of thailand as you need proof of current location (eg arrival stamp)
