Abstract
We discuss a comment recently made by C F Lo concerning validity of one of the examples used in our paper (2013 J. Phys. A: Math. Theor. 46 235301). While we agree with Lo's statement regarding inapplicability of the example to the proposed schema, we disagree with the claim concerning mathematical correctness of that example. We are not convinced by Lo's arguments leading to the conclusion that the model is mathematically ill-defined.
