It is more a matter of convention than logic. To the extent that there is logic, it might run like this: An image is a string of bytes representing pixels arranged like letters in text, starting from the upper left. When no explicit X and Y vectors are given, contour and pcolor are implicitly using the array indices as X and Y.
