It was a very wrong analogy. I could say that a barn full of pigs is an analogy for a car engine. Just saying its an analogy doesn't fix it. An analogy is meant to help people understand something; the analogy presented helped them misunderstand.

You've done a lot better in your correction of it, but in doing so you've had to basically render the analogy worthless. There is no analogy for what's happening. It's simpler and clearer to just state the facts.
