"to tell them why your product or service is better, and to do so in a way that is easy to understand and meaningful to them"  是 the point的同位语。

参考译文：美国人希望你说到点子上，告诉他们为什么你的产品或服务更好，并以一种容易理解和对他们有意义的方式告诉他们。

to tell them why your product or service is better, and to do so in a way that is easy to understand and meaningful to them ——

是前文不定式 get to the point 的补充性状语，用来解释、说明或例举 get to the point 的。不是get to the point 的同位语，更不是 point（点）的同位语。它们没有“同位关系”。
