I try to add a little bit here too:The part of the rulebook you are referring to is just there to clarify previous rules. Because there is the rule that units in areas with a activation token cannot move. So this paragraph just wants to emphasize that you still CAN recruit in such a region.
Note: (I say this, because I can remember a discussion about that a while ago) This does not mean that you can recruit in areas that have an activation token ONLY! You can only recruit in areas with a friendly stronghold. If this area with a stronghold happens to also have a activation token, recruitment is still possible. But those newly recruited units CANNOT move anymore this year (since units in areas with an activation token cannot move)
If you have any more questions, don't hesitate to ask :)
