Maybe the article is being vague but stuff like this really doesn't seem like it should be patented. Especially considering I'm pretty sure I've seen this done in games before. The simplest being Mario games giving you invincibility in a level after you die a set amount of times. Or I think A Hat in Time would shorten certain boss battle segments after you completed them already.
The implementation here would need to be really new and impressive to justify this being a patent. And I'm guessing it won't be, assuming they ever actually do something with it.
