There isn't any class documentation on this attribute and doesn't seem to have an effect on the output. What is the purpose of this attribute, is simply to give a unified API between the 1D and higher order interpolators?
I think I meant for this to be similar to the axis property of Interpolator1D and the various scipy-like classes but never actually implemented it. I'll try to add it in the next release
