Dragging the zero point to a new location will not work in rotated spreads
If you rotated a spread view and you want to move the zero point from the origin to a different location the landing point is never the one you dragged the cross-hairs of the rulers to.
It needs a sophisticated script that will workaround this bug. Currently I'm writing one, that should overcome this issue.
Nevertheless, that should be fixed.
Watch the movie clip where I like to drag the zero point to a new loaction and always fail.

I see this bug with InDesign CS6 through to the current version CC 2018 18.104.22.168.
Tested on OS X 10.11.6, but I think, it's also on Windows OS.
