I completely agree with you.

No matter the cardinality of the space the rover is operating in, its coordinate is always a point.

If its world is 2-dimensional, you’ll be able to describe its coordinates with two numbers;

if it’s 3-dimensional, 3 numbers would be required; and so on.

Unfortunately, the authors decided to put the rover in two places at the same time on a two dimensional map (c.f. the @Before annotated method)

– once at (1,9)

– once at (2,9)

those positions seem to be mutated independently depending the direction and command

It is either the authors meant to say that the rover is a photon or something else that allows one instance to manifest itself in two different places at the same time, or the example is incorrect if designed to be applied in real life.
