これに対するレスが、

There was a leak in IronPython where we were keeping COM objects alive once the IPy code manipulated the COM object. The code in the blog seems to be dealing with this bug with the use of the auto method which calls Marshal.ReleaseComObject in the finally. The bug is fixed in the 2.0 tree and so it should be possible to shorten the code a lot and end up with just a few levels of nesting.

リークはバグですか！？ withステートメント技は無意味ですかーっ

Well, still a good use of "with" for an elegant workaround :)
