I agree. They didn't show any slight bit of worry or surprise for that matter when Shanks showed up in Mary Geoise of all places, whereas Sakazuki nearly shit his pants when he surprised everyone in Marineford. Also, its a small detail but they asked the guards to leave. Of course this shows they wanted privacy but to me it also indicates they don't need their help if he thinks of attacking them, or they honestly respect him enough to know he wouldn't do something like that. I think its a bit of both.
