Stacking 210 cabs vs 410

[BassAdder60]

I am aware of the situation of a single 410 cab and having the four speakers layout but what is the improvement if any of stacking two 210 cabs ( horizontally) where the two sets of speakers are further apart than in a single 410 box if that makes sense ? 
see image as example and in my case both tweeters would be off 

 

im aware that vertically stacking is better

There's no advantage to that over a 410, as it's essentially the same thing. In fact the increased spacing is worse. If you must do it, though I can't imagine why, the bottom cab should be flipped upside down, placing the woofers closer together, but only if the tweeters are not used. If they are used the top cab should be flipped, placing the tweeters closer together.

Thanks Bill 

 

So vertically stacked is better in addition to speakers being nearer to ears but any other reasons ?
