Nice explanation. This question is receiving a lot of views (probably not everybody being as proficient in bash as the others) and I believe no-one yet spent a couple words on what { :;}; actually says. That would be a nice addition to your answer in my opinion. May explain how you get from your example to the original command in the question?

comment What does env x='() { :;}; command' bash do and why is it insecure?
Up until this moment there has not been an accepted answer. I'll probably wait for another couple days before accepting one. The downside of this answer is that it doesn't break down the original command, nor discusses how to get from the original command in the question to the commands in this answer, showing they are identical. Apart from that it is a good explanation.
