Obi-Wan knows that Annikin is pissed about people trying to get him to leave, since Annikin made it very clear that he wasn't going anywhere. If Obi-Wan had pushed it even more, he risked either look like someone with his own agenda or someone who was furthering Sarus's agenda, which is something he considered in the text before talking to Annikin.
