He intended to fight Orochimaru. Kinglink15 wrote: maybe he just didn't bother with it as he never thought he could do it as good as Minato or Tobirama. Seems like it's this. The jutsu is not that strong on it's own, and opens up the user to counterattacks and whatnot. Tobirama and Minato developed a considerable repertoire around it. Hiruzen didn't.

Thanks for the clarification
