Although I think Juliette is really ostricized by Others for good (remember she killed one of them), it's possible that she's playing her part in Ben's game, trying to make Kate and Jack think she's left behind while her intention is to go spy on Losties by the beach. Perhaps, Locke and Ben's conversation by the Black Box lead to sharing of precious information off-screen and Ben thought it necessary to get Juliette spy on Losties' camp. If that's the case, I'm thinking, EITHER that Others went underground into another hatch or left the terrains secured by the fence and either way, had to have the fence turned off and Juliette knowing that, had to activate it after encountering Smokey---
OR, It was never off anyways, but the side with the control panel was off the circuit (otherwise kind of difficult to approach and alter it once it's been set)
Yeah, the security fence must allow for a bubble-like protection that Smokey can't do much about.
