Not to nit-pick, but I think it is even a little more clear like this:
Gold: steps one square orthogonally or diagonally forward
That's what it says already. The reason I think that's unclear is that 'forward' could be taken as referring to the whole of 'orthogonally or diagonally' rather than just the latter part.
