The Vedic Injunctions and Desire

In the case of Kamarila, yes. It's a universal claim about human actions. In this sense he will speak of desire as the identifier of the one who is eligible to perform a sacrifice. And in this sense, please note the fact that there's no guarantee that you'll get the result of the sacrifice. The desire is only important to identify you as the one who has to perform a given sacrifice - even if you might not get it at the end.
