Because one common assumption was that the universe might contain as much antimatter as matter.

Which begs the question: Where did it go? We would notice a huge amount of annihilation reactions in the solar system.

"Antimatter falls up" (is gravitationally repelled instead of attracted by normal matter) was an easy hypothesis to explain that.
