Well, actually, he was established to be able to use it at least three times in a row before the recharge. But, on the other hand, Sasuke falling into the hands of Shin was much more dangerious prospective than Sakura's kidnapping. Sasuke was immobile back then, so it would've been no trouble for Shin to extract his Sharingan/Rinnegan. And since Shin can easily accept any foreign genetic material thanks to his unique body, a villain with the Rinnegan would've been a truly fearsome scenario, along with Sasuke losing his eyes and subsequently being killed or used to experiment on.
