Not only do they appear to be the same, they are equal. Note that the data in your file might not be exactly down-to-the-last-bit identical, but I'd expect the norm of the difference between the two to be very, very small even if it's not exactly 0. That indicates they're very, very close together and so as Star Strider said their plots overlap.
