The firing order is 1432, so it does alternate sides.

maybe this is why the DP motors had separate Ports. but they still share that same tube closer to the carb. I THINK its more difficult to do it on the cam. 1423 or 1324

It doesn't matter which cylinder you're starting with, the way VW designed it is that two cylinders on one side are fired in succession before the two on the other side are fired, i.e. 3 follows 4, and 1 follows 2. The cylinder being fired alternates from left to right bank only once in the 4-cylinder cycle.
What Mr. K is asking is why doesn't it alternate sides after each time a cylinder is fired so that the fired cylinder alternates sides twice in the 4-cylinder cycle.
In a water-cooled car where the cylinders are inside the case you don't want adjacent cylinders firing in succession -- thus avoiding localized heat build-up.
