No, he's referring to the fact that Toriyama originally wanted to end the series at the Frieza saga. The idea behind it all was that Goku would prove himself the be the legendary SSJ, defeat the the most powerful and feared being in the universe (Frieza) proving himself to be the strongest warrior in the universe, and then die when the planet blew up.
Of course, the series was so popular, that Toriyama was forced to continue to story beyond it, in which he made every saiyan a super-saiyan and Frieza was no longer a big deal.
