Perhaps it's better to put this into another perspective. Take human behavior, for example. Is human behavior static or dynamic? Jungian type attempts to cover both at the same time, which is paradoxical to reason or sense; it is nonsensical; and how you interpret the nonsensical is your own prerogative.
Now infinity is dynamic and numbers are static. To say that infinity is both dynamic and static is nonsensical. So how you interpret it is what it's going to be or mean. The nonsensical is the dualistic opposite from logic. The difference is one operates on axioms and has self-evident meaning and the other doesn't.
Do you understand now?
Edit: Editing out reason as being opposite from the nonsensical because reason is the capacity to understand something, which does not have to be logical. So perhaps it's better to say that reason can be both sensical and nonsensical and that: "The nonsensical is the dualistic opposite from logic (and not reason)".
