It sounds like everything had been taken care of for her, which simply means the person was "crazy" enough to commit herself to an experience that a lot of people either wouldn't want to do, or didn't have the time to do. The article does not mention it, but I am sure this person has her life structured in a way where she was able to (financial and responsibility wise) do this without a second thought because "being quiet" is also part of her personality.
Not to discount her record or anything, but it's nothing more than a record.

I don't mind the downvotes btw, but let me just point out that Yogis live in caves for 30 years at a time, and good luck earning their trust to let some scientists monitor real changes in the mind.
And these Yogis do so without any assistance from the external world. That sounds a bit more impressive to me.
