Because they moved the Godzillasaurus to the Being Sea. They didn't move the Godzilla that, in the prior timeline up to that point, remained in the ocean/volcano in this hypothetical. So the Godzillasaurus in the altered timeline was never in the volcano. Because in 1944 they'd move him elsewhere. Meaning he'd be created elsewhere and never imprisoned.
