I think the IT industry is filled with broad, vague clauses like this that aim to lay claim to all IP an employee creates (which can include art, music etc. as well).
Some employers make the excuse that it's only during office hours; others claim that this clause would "never actually be used".
In my experience it is rarely removed. I've turned down jobs because of it and others that I have accepted I have been extremely worried something like this would happen. I feel for the employee in question and hope they are able to retain control of their open-source code. Maybe this bad publicity encourages others to push back in the future because I generally find this behaviour quite unacceptable.
