Lisp_Object is a 64-bit machine word. For pointers, because heap allocations are 8-byte aligned, their lowest 3 bits are guaranteed to be 000. Emacs simply embeds the 3-bit type tag directly into these "free" zero bits. For immediate integers (fixnums), the upper 62 bits hold the actual value.
The other problem is that in practice, it’s surprisingly easy to write code that implicitly observes some state without having the proper dependencies, at which point glitches appear again. There’s typically no easy way to fully prevent these cases from cropping up, so some amount of vigilance is required to make sure everything is working.
