He probably meant ghash went down so he joined mmpool as an alternative.
Yes and your suggestion to join mmpool has made my life really interesting.

I found a problem with zencloud-gawminers due to using and testing mmpool with westhash purchased hashing along with using the asicminer tubes.
I do not know whether to like you or be mad at you. Well the flaw I tested for in mmpool does not exist but there was a huge flaw in part of zencloud-gawminers product line. They had to end/transfer all of the nicehash section of their business.
That was an interesting post- got me to try pointing my tubes to mmpool (where they've been miraculously stable compared to the other pools I'd tried them on) and that zencloud bug made for quite interesting reading as well.
