A problem in official website 'Least-Squares (Model Fitting) Algorithms'

Under 'Levenberg-Marquardt Method', it says 'Consequently, for some sufficiently large λk, the term F(xk + dk) < F(xk) holds true'. 'F(xk + dk)<F(xk)' should be corrected to 'norm(F(xk + dk))<norm(F(xk))' . Right?

... f(xk + dk) < f(xk) holds true
