I don't know if I can get behind .71 implying "correlates really well" ... that's the issue I had recently with talking with GPT, it was evaluating my logical reasoning ability based on the vocabulary I was employing. You don't need fancy words to be intelligent.
I think people don't often have a good intuition about what different correlation coefficients actually look like or imply.
.71 explains about 50% of the difference, its bigger than the effect size of Advil or Tylenol
