I don't think it's a mistake. He's claiming that it's faster than C++ and it's faster than safe Rust.
The extra "than" in front of "safe Rust" is superfluous and reads like an error, as if there's a comparative adjective missing ahead of it. I don't see any situation where "and than" should ever appear in any non-contrived English sentence.
