In object oriented code, this can happen often, but it is not a problem. It
does what you want : inverse the axis, even if there is only one axis.

More code in a simple function (thus slower) ? Breaking some code that
depend on it ? Not doing what the documentation says ?
I think the method should not be changed, it does exactly what it says it
does. Changing its behaviour because of Matlab is not a good solution,
Python is not Matlab.
