I don't think that's true; it's just that when you render the image normally it takes the alpha into account, so it *looks* like some of the pixels aren't there. Modifying the alpha channel directly would reveal the pixels. Keep in mind that most Mac graphics programs (well, probably except Adobe's) are using the system libraries to read standard file formats.
