It makes it simpler, but does it also make it slower? Seemed that the blog's point was that communicating between windows is slower in chrome than in other browsers because of this behavior. You simply further explained why, and confirmed that it is only in chrome. Right?
Now, I do think there is room for argument that this is a better way. But you do not seem to be undermining any of the blog's points. Those being that chrome has a slower process to communicate between windows, and that it is the only browser that does this. The frequency with which this is needed was not a point of contention.
