The x=DataArray example looks like a bug.

The last example raises a MergeError regardless of the order of x, y which is good I think. It's pretty ambiguous to change both the index x and the y=function(x) at the same time. It will only work if xarray uses magic and infers that everything but x must be assigned before assigning x.
