Developer of NeedCoolerShoes, the site in question here. Yes, absolutely correct, spot on! For anyone else interested in researching this more, the technique is called farbling.

In fact, as my tool also has layers, this subtle noise would compound with each additional layer added, until the noise was not subtle at all.

I received many bug reports about this, and it took me ages to track down the root cause, by asking users what browsers they were using and joining the dots.

I do worry that maybe I worded the popup poorly leading some more skeptical folk to worry my site was attempting to fingerprint them, which it is not.
