I thought the CM current in question came from the antenna in the first place.

It depends whether it's receive or transmit. The principle of reciprocity applies. As I've tried to emphasize, the most important reason for using a choke is to suppress RX noise, but by suppressing common mode current during TX, we minimize crosstalk to other antennas.
