The key to what's going on is the call to pixels.reverse(). When you call getRGB() on a BufferedImage, Java hands you back all the image's pixels in a one-dimensional array. Simply rewriting the array in reverse order has the effect of causing the image to paint lower-right-corner-first (if you know what I mean). It rotates the image 180 degrees.
