Musk has a long history of anti-semitism [1], and has showed support to the AFD in Germany, a political party directly linked to neonazis. He knows some neonazi-adjacent guys usually attend Trump rallies, and this "nazi-ish salute" might be a dog whistle to catter to them.

Or it could not be, and he'll certainly deny it was. We'll never know for sure, that's how a dog whistle works.
