And the subtype relations work well too: D-N is a frequent combination in couples, so is H-C. It's all about taking the time to observe this, and understanding what to look for, but I don't think anybody can prove this. If you can get to know people of your own type but with all 4 different subtypes, then it's a good start. When you get further you can use 8 subtypes, it's often quite easy to distinguish between for example Ti- and Fi-normalizing etc. The really cool part is to see how these things occur in our culture. Gulenko has some examples, but it is easy to think of more.
