Thank you for your input @mo-vic , but that is correct. The "iff" here means "if and only if". What that sentence is trying to convey is: for any two lanes with indexes j1 and j2, if and only if j1 < j2, then the point closest to the bottom of j1 will have a smaller x value than the one in j2, which means that the lane j1 is closer to the left border of the image.
