Class A2 Tube Currents

This should be a simple question for someone. I just want to confirm my understanding of the changes that occur in an output stage during the A1 to A2 transition. Please correct me if any of the following are incorrect:

When an output stage transitions from A1 to A2...

1. The output tube draws grid current.
2. The driver delivers power to the grid.
3. Average cathode current increases.
4. Average anode current does not increase.

Is this all good? If so, I would also be interested to know whether there are anomalies in practice that do cause anode current to change when the tube enters A2. I assume that would be measurable as THD, but maybe I haven't fully thought through the process.
