Generally speaking, it's better to design for simplicity and maintainability of code rather than optimize for speed from the outset, especially in the case (like this one) where either approach works. There is no Android rule-of-thumb that says "don't use multiple activities", although I've seen a number of people on this list get that impression from the documentation you quote. Lots of Android apps have many Activities and that's fine.
So in your case I would recommend that at least for the screens that share nothing in common, use different activities.
