Data knows where Juliana is - with Vaslovik. Soong saw them together, and Data has Soong's memories. He has no reason to believe that his search for Vaslovik won't also reunite him with his mother.
All I'm saying is that, technically, all Data knows is that Soong remembers seeing Juliana and Vaslovik together in 2375. He doesn't know the circumstances in which Vaslovik's mansion burned down, and he doesn't have confirmation that Juliana survived the Borg Invasion.
Just because Juliana was with Vaslovik in 2375 doesn't mean she's still with him nine years later.
Assuming Juliana is either inactive or no longer with Vaslovik for some other reason, the best way for Data to learn any of those things is still by finding Vaslovik himself.
