Nope. They're literally measuring two different things, return rates vs "would tell a friend" rates.

Whether those two happen to coincide is quite product-dependent. Finding examples where they significantly diverge is trivial.

A recent example of this is Peach.

Did people want to tell their friends? Yes, but not because they loved the product. Because they wanted to be seen as cutting edge.

Most of the product hunt/tech crunch circle jerk is stuff like this. Lots of fluff with short-term spikes but little long term retention because the product doesn't solve a real need.
