No, actually. I have no idea why you're relying on a quote 8 years prior to him starting writing 1984.
https://en.wikipedia.org/wiki/Nineteen_Eighty-Four
> In his 1946 essay "Why I Write", Orwell explains that the serious works he wrote since the Spanish Civil War (1936–39) were "written, directly or indirectly, against totalitarianism and for democratic socialism".[3][89] Nineteen Eighty-Four is a cautionary tale about revolution betrayed by totalitarian defenders previously proposed in Homage to Catalonia (1938) and Animal Farm (1945), while Coming Up for Air (1939) celebrates the personal and political freedoms lost in Nineteen Eighty-Four (1949).
> In one 1948 letter, Orwell claims to have "first thought of [the book] in 1943", while in another he says he thought of it in 1944 and cites 1943's Tehran Conference as inspiration: "What it is really meant to do is to discuss the implications of dividing the world up into 'Zones of Influence' (I thought of it in 1944 as a result of the Tehran Conference), and in addition to indicate by parodying them the intellectual implications of totalitarianism".[13] Orwell had toured Austria in May 1945 and observed manoeuvering he thought would likely lead to separate Soviet and Allied Zones of Occupation.[14][15]
> In a June 1944 meeting with Fredric Warburg, co-founder of his British publisher Secker & Warburg, shortly before the release of Animal Farm, Orwell announced that he had written the first 12 pages of his new novel.
Keep on reading that wikipedia page, which explains in detail all the characters, agencies, events, etc in the book that are in many cases directly taken from elements of Stalinism.
