Why did he skip to measure the south? He should have measured the west before it!

Malbim: Just like in the wall of Ezras Nashim, the north, south and east walls were the same in their gates, cells and Ulamos, and the west was different, it did not mention measuring the west. Also Har ha'Bayis, the west was different in its gates and Binyan. Therefore, before it, he measured the south, to see if it is exactly like the north.
