Itachi knew Sasuke would want the eternal mangekyou and that he would transplant the eyes. Now after the transplant, Sasuke wouldn't have Itachi's mangekyou eye patterns, but yet the crow would emerge and Sasuke would've gotten one shotted provided he attacked Konoha as according to Itachi himself. Nope, the crow only appeared when Itachi manifested his Mangekyo, not when Naruto and Itachi were in CQC.

Also Sasuke literally has Itachi's pattern in his eyes lol, that's what having the EMS does.
