I think it's because his Q is a targeted skill-shot, so when you target Q on a minion to hit the champion behind it (who you've been autoattacking up to casting Q), you have the option to either use the doubleshot on the champion or the minion. If he resumed autoattacking automatically, then you would always be attacking either the minion or the champion after the Q, which may not be what you want depending on the situation.
