In the second match on Terminus RE, I don't understand why glade chose to take his 3rd expo at the 9 o'clock spawn rather than just taking his natural 3rd and maybe even his 4th. It's far harder to saturate and defend, and its use for army unit production is very inefficient. When going muta/ling I find having a good supply of larvae and without a close 3rd or auxiliary hatchery production of units becomes far slower. You can see half way through the game when he starts panicking and places a hatch at the natural 3rd and 4th but by then it was too late. I think maybe grabbing a 4th might be a problem in the middle of the map because it is too hard to defend from a marine/tank push but I really believe that the best 3rd would be his natural one.

Could someone maybe explain his reasoning behind taking the 9 o'clock spawn as his third? Was he trying to hide it? Is it because theoretically once saturated it provides greater income?
