The documentation you have been futzing with is about the fact that the initial set of known to be good/bad commits that "git bisect start <bad> <good>..." take can have one bad and zero or more good.

What is being discussed in this thread is different (and I tried to clarify the fact by saying "what bad and good commits in what sequence").

Ted is talking about replaying the series of "git bisect (good|bad) $a_single_commit" that are recorded during a bisection session and can be read via "git bisect log". When Ted says "good commits" and/or "bad commits", he is not talking about giving all of them to a single invocation of "git bisect" command. The replay session will take one commit at a time (which is what "git bisect replay" does) and feed it to either "git bisect good" or "git bisect bad".

Does it make sense?

By the way, I do not think there is anything to regret in asking what you do not understand. Showing how much you know (and you don't) will allow others who communicate with you to calibrate their expectations, which eases later discussions; it is a good thing.
