I don't know what you mean by "rerouted". The .dll contains 6 separate functions. One of them is "aWarpSharp" (the older version of the sharpener that had a few glitches with some videos, like turning borders green) and the newer version called "aWarpSharp2". What's not to get? If you go to the html doc at
http://avisynth.nl/index.php/AWarpSharp2 or look at the docs that come with the plugin, you can click on those two functions for details to see how they're similar in some respects and different in others.
If you wanna see how warpsharp differs from other sharpeners, try the AMV site's discussion of different Avisynth plugins where three different sharpeners are demo'd, with image changes each time you click on a filter's name:
