In real life Soviet Union, they did have such occurrences where more than one person were plants. Maybe in Cointelpro also.

I don't doubt it, but it isn't hinted at in "1984". The only thing I will grant the authoress is that Julia was bored when Winston was reading aloud from the book given to him by O'Brien, so she was more interested in having a freer life than in understanding the underpinnings.

Winston was pretty low-level to expend that much energy on. Having multiple operatives when Winston's journal was found, when Charrington was also an operative with an unseen telescreen, is overkill, even for IngSoc. The "Julia" twist sounds like something more suited for #6 in the Prisoner than "1984", and it changes the meaning of the story if Julia is also an operative.
