Misplaced parenthesis in loss calculation?

t = alpha * reshape((1-o(c_)).^gamma, [sz(1:2) 1 sz(4)]) .* (log(sum(ex,3)) - reshape(x(c_), [sz(1:2) 1 sz(4)])) + xmax;

It trains fine, but the loss increases. I think maybe the last closing parenthesis should be moved to the end, like so
t = alpha * reshape((1-o(c_)).^gamma, [sz(1:2) 1 sz(4)]) .* (log(sum(ex,3)) - reshape(x(c_), [sz(1:2) 1 sz(4)]) + xmax);
