The next step is to modify the argument deduction to retain information
about the "rvalueness" of the argument: when deducing against a template
parameter of the form A1 &&, deduce A1 as a reference type when the
argument is an lvalue, and a non-reference type otherwise. According to
our T cv1 & cv2 && == T cv12 & rule, this effectively means that the
type of the argument will be A1 & when the argument is an lvalue, and A1
&& otherwise.

どうやら右辺値参照パラメータに対する特別なdeduction ruleみたいですね。
