to is not a typo here. It's saying if we have a reference to another object, then mutating it will affect all other variables that contain a reference to the same object.

Thank you for your interest in contributing to the curriculum.

I agree with Mao here. This isn't a typo and the proposed change alters the sentence in a way that doesn't make sense. If you find the sentence's construction confusing, we could potentially discuss a different way to word it. If it does make sense to you now though, I'll close this PR down.
