Why require the second call returns an object and not a class?

Question

Node.js

Good day! There is the following structure of modules:

Module1 acts as the main one, Module2 and Module3 are children, BUT the child modules also recuar each other.
The problem is, in the main module, requare normally connects the child module and returns the class. In the children (apparently the second time) it returns some kind of object.
I read that requare works like requare once and caches everything. Why doesn't it return a class to me, but some kind of object?
