A DX sensor will not produce images with a different field of view with an 85mm FX lens than it does with an 85mm DX lens.
But an FX sensor, using either of those same lenses will produce a very different image in terms of field of view.
That chart, and the calculator that I referenced, both clearly demonstrate that your statement is not correct.
:oops: I see my error. My edit of your previous comment should read "And if you stand in one spot and make a shot with an APS-C sensor camera using an 85mm DX lens, and then make another shot from the same spot with an 85mm FX lens, the two images will have exactly the same field of view." Obviously the field of view with an FX lens on an FX sensor will be about 1.5X greater. I'm glad you pointed this out, I do not wish to confuse any newcomers.
