I think it should work this way
What if the original entities has coincident to the original point (origin) and how to copy it to a new location?
Another option is to provide options which coincident(s) is copy or not - but it'd be complicated !!!!
I do indeed have automatic relations turned on.
I also have the "Keep Relations" checkbox enabled on the copy command, although I did not expect it to do anything in this case.
Below are 2 screenshots that illustrate the issue I'm having. Notice the yellow coincident symbol in the first screenshot. Same result on SW 2015 and 2016.
