its logical mate.. his speaking about his time space jutsu , not about his full arsenal
time space jutsu could possibly be also someone else's technique that he either absorbed or stolen.
Quote: According to Minato Namikaze, Tobirama was also highly skilled in Space–Time Ninjutsu.
Someone already tried to say that he might have been absorbed by Tobi, but this theory has a flaw because he was summoned using Impure World Reincarnation by Orochimaru.
He was also the creator of the Summoning: Impure World Reincarnation technique.
So it's logical that someone would claim that Tobi is the Second Hokage, but ones again, he was summoned using Impure World Reincarnation by Orochimaru.
My guess/theory is, Tobi is a clone of both Senju (first and second Hokage's DNA) and Uchihah (Madara and maybe his brother's DNA), but because he was brought up by Madara, he didn't know or wasn't taught anything about the Impure World Reincarnation.
That's just an assumption.
