It definetely wasn't their first fight anyway. Not even the first fight with EMS by Madara. And in the VoTE Madara already had Kurama as his tool, which power is roughly the same as that of PS. Moreover, Kurama needed some protection against Hashi's Biju-controlling powers of Wood Release, thus his MA:S for Kurama. If he used PS and Kurama independently, it'd become a chance for Hashi to quickly disable Kyubi, and Madara surely didn't want to lose his precious tool at very beginning of their battle.
