Theorem xblss2 22987
Description: One ball is contained in another if the center-to-center distance is less than the difference of the radii. In this version of blss2 22989 for extended metrics, we have to assume the balls are a finite distance apart, or else 𝑃 will not even be in the infinity ball around 𝑄. (Contributed by Mario Carneiro, 23-Aug-2015.)
