The information provided was inaccurate. Riot made many unannounced changes on the PBE as to how spell-swapping worked, and the current method was not documented and so this page was inaccurate. As tested in-game (December 7th), casting Heal (for example) will put Heal's slot on cooldown, and you must wait-out Heal's cooldown even if you swap spells.
