Wouldn't that be easy to foil? I can, and do, write with different styles that depend on the audience I'm trying to reach. I'm reasonably sure I could write entirely unlike my normal writing and appear to be a completely different person. I've done a lot of writing for very different audiences.

Am I, perhaps, over-estimating my ability? Are they really that good at determining origin?

Even if you're overestimating your ability, it does not really matter for the case at hand. You can have someone you trust write the review for you.
