Hello for this example we see a coordinate grid which helps us identify the position from my understanding normally we go in the order (x,y) in this practice the correct solution was in (y,x). I was wondering is there any particular reason for that or does it not matter?

When making calls to the Get path to function, we are providing the x and y coordinates (the x coordinate is the first argument, the y coordinate is the second argument) of the target location.

After making a call to the Get path to function, when moving to the retrieve the key, Codey moves up and then right.

When moving to the door, a fresh call is made to the function and Codey moves right and then down.

So, it doesn’t seem that the function is preferring up/down motion over right/left motion or vice versa.

If this is not what you are asking about, then elaborate a bit more on your line of thinking.

When making a call to the function, we must provide the x coordinate first and the y coordinate as the second argument. The order matters.

When the function returns a path, there doesn’t seem to be a bias about which direction we move in first. We don’t really know the logic that has been implemented inside the function, so we don’t really know why Codey moves up/down first in some cases and right/left first in other cases.
