In what way is it misleading? The original title and abstract are beyond my knowledge.

In that they did not reverse aging. They affected one aspect of aging in a significant way, but did not completely stop or reverse it. And it was only in one type of tissue, and they don't know that there won't be dangerous side effects. There are still many other aspects of aging that they did not affect.
