This is similar to the Gibson / PRS legal issues re: Les Paul vs. Singlecut body shapes that surfaced a few years ago.
As customer who owned both, I was contacted via phone for an interview by PRS and was asked the specific question: "When you made your purchase, were you at all confused by the similarity of the body shapes?".
To which I responded: "Absolutely not. I purchased each instrument because of its specific capabilities. To me, they both look, sound and feel completely different from each other".
For additional proof, try to fit a Singlecut into an LP case (and vice-versa).
At the time, I thought it was a nuisance lawsuit and was disappointed to learn that PRS could not sell or promote the Singlecut model while it was going on, but Gibson was not similarly restricted re: the LP.
So I agree - I do not think a knowledgable customer would be confused by any perceived visual similarity between the Exploiter and Explorer.
