Not true. In the early years of the Oscars the acting awards and some others went to the person, not a specific performance in a film. So Janet Gaynor was Best Actress in the way a baseball player was Most Valuable Player, and then their films from the eligible time period were listed-- so for Gaynor it's Sunrise, Seventh Heaven and Street Angel, for instance. But basically there wasn't official recognition of the films at that point-- the listings of films were largely informal as were, for that matter, the nominations.It marks the only time in Academy history that an actor competed against himself in two separate films.
Without going into every possible permutation here, let's just say that obvious inconsistencies quickly appeared, some awards were treated differently than others in some years, and in general they made a big muddle of it. They finally cleaned it up c. 1930-1 and made all awards for a single specific performance (or directing that film, shooting that film, whatever), as well as pruning some of the nominations and so on. History kind of agreed on certain things-- that Arliss won for the very highly regarded Disraeli and not the less admired The Green Goddess-- though some sources will list both. Either answer is technically correct.
