Let the rational function $f\left( x \right)=\frac{p\left( x \right)}{q\left( x \right)}$ consist of two horizontal and two vertical asymptotes. Then, the degree of the denominator term will be two since the function has two vertical asymptotes. And, for having horizontal asymptotes, the degree of the numerator should be either equal to or less than that of the denominator, and in that case we get a single horizontal asymptote. Thus, it is impossible to have more than one horizontal asymptote. And, therefore the given statement does not make sense.
