A lot of text understanding has to do with things like "A Theory of Cognitive Dissonance (1957), Leon Festinger". Reading is making sense into texts. https://en.wikipedia.org/wiki/Cognitive_dissonance
And you assume that the author, you assume this for a math author, that he doesn't give you an anyway false list of statememts.
The much simpler example is this:
3 = 3/1
We compare a rational number and a natural number. Strictly speaking the above statement is false, if we see ./. as an abbrevation
for the usual pair construction of rational numbers, because N and N x N are usually disjoint, also equaivalence class from P(N x N) are disjoint
to N x N. So implicitly we all the time move objects from one type to another. Otherwise we would just read nonsense.
