Thank you for the contribution, I think it is a good piece of work, I have some comments.

This is a duplicate of the test above, I would suggest keeping just one of the implementations.

The ordering of the input arguments are a bit hard to read, perhaps we should reorder them?
Secondly, having arguments with 1 and 2 can very often lead to bugs, so perhaps we should try to avoid that also?

One option is to just keep the tuples, that might make it more readable.

Would be good to add a docstring, as it is not immediately apparent. Also the name is not very descriptive.

Your style check is failing, one reason is because we are missing type hints in this function.

There is a potential bug here if the x-coordinate does not change. Should also add a test for that.

This line is a bit confusing, perhaps it is worth rewriting?
