Now I'm confused!

I supposed so (as you've quoted above), but then I tried it and have seen that pushing up exposure in ACR creates a lot of noise. Also creates too saturated high contrasted images, and the DR is less than the ISO boosted image. The pushed up results of course include manipulation of ACR itself in terms of other IQ settings (twisted color profiles), but I assume, if I had used an untwisted version of ACR, the results would be still worse than the ISO boosted image.
Walter, I've checked the links you've sent. Thanks a lot. I've found some untwisted profiles for D700 and placed them under the related folder to be used in ACR. But apart from the difference regarding the "recovery" slide, the result was more or less the same. I did not have much time for a thorough check but at first glance it seems so...
