It's not clear to me what that ApplyPatch method is doing under the covers. It's not MsiApplyPatch(), because that does an install of the patch. It appears to actually be MsiDatabaseAplyTransform() judging from the transform parameter, and that just modifies the tables.
This might help: http://blogs.msdn.com/b/heaths/archive/2006/02/14/532200.aspx particularly where he mentions using MsiOpenDatabase on a patch file and then looking for streams.
