Laravel "knows" to fix wrongly capitalized relationship name?

I accidentally named my relationship at first with PascalCase:

public function MyRelationship()
{
    // return ...
}

and also used it in some parts of the code: Auth::user()->MyRelationship->some_column;

But then I renamed the relationship to camelCase:

public function myRelationship()
{
    // return ...
}

but didn't change the code invoking it, and it still worked. I tried to use both myRelationship and MyRelationship and both work
