Sky pointer

Can some one please explain why in commercial AC the sky pointer will point in the different direction.

I know that it has been like that for ages. But it really seems stupid.
In GA and military AC the pointer points in the correct direction.

There is an interesting small study regarding roll reversals with the commercial ADI.

In the study the conclusion is that the pilots in the test made 5 times more mistakes with the commercial setup, than the GA/mil setup.

Also there are speculations about some accidents caused by loss of spatial orientation.


But what I am wondering is why,even after we know that there has been accidents caused by the effects of the sky pointer, it is still used in commercial aviation.

What are your thoughts regarding this.
I have little or no experience regarding the commercial sky pointer other than some sim training and FS,hehe.

Edit: Here is the link to the study
