Just a small cosmetic change. Since there is two subtraction operations side by side, I thought it might useful to clarify the order of the vector operations. It might prevent bugs when this code is being used as a reference for other language implementations as the operator precedence behavior might vary.
Thanks for the contribution, however I do not agree with the justification for the change and I don't think it improves the code. Sorry, but I'll close this one without merging.
