I don't have perfect pitch but I can tell you without a doubt that A Warm Place inverted sounds almost nothing like The Downward Spiral motif.
There are some small similarities. If there is anything here, the music has been extremely twisted to the point of non-recognition. This may be the point; TR has been known to self-reference often.
The Downward Spiral was even released in reverse on the Not The Actual Events vinyl B-side. Listening to that, it doesn't resemble A Warm Place in the slightest.
