If he'd had more on him, he'd have tossed them all out anyway. The Pokemon League just figures that six is a good upper limit for fantastical creatures that the average person can look after responsibly at any one time, and in the games the player adheres to that for game balance reasons. Not that it matters much in the present day where the PC box is accessible from anywhere.
