I don't think it's nearly as clear cut as that. Neutrality means you're willing to work with whoever wins. It requires a high level of moral ambivalence.
If you are actively aiding one side or the other (or both), I don't think that counts as being neutral (if it does, it is certainly a very weak form of neutrality). Which is exactly what Sweden has done and is doing, dating back to at least WW2.
An isolationist policy leads to a neutrality that doesn't necessarily involve working with the winner.
Oh please...is Sweden so socialist that there's an ambivalence of western vs eastern bloc ideology?
