If you will do something different with a 5 than with an 8 then yes. If not, then the ambiguities you describe will be worked out when you do the work. It is just a vanity metrics if the results doesn't change what you work on next. It seems important but it has no actual bearing on the teams sequencing of the work.

If Bob had a plan for doing the work that didn't involve Alice's library, there's a good chance he would have just jumped straight in to implementation without talking to anyone, and maybe the library wouldn't have come up until code review (if at all). By identifying the complexity mismatch ahead of time, they saved 3 points worth of effort. This doesn't affect sequencing at all, but still seems valuable to me.
