Once again, you lack context. You don't know why it's happening. I'm not saying it's good that Oda did this without explaining, but there is a reason for it
Read the last 2 pages of 1037:
Entire goal was to capture Robin
Then a page later it's about Luffy.
Then in 1041 they tell the CP-0 guy to drop his goal for capturing Robin and go after Luffy:
Something caused them to go from Robin -> Luffy.
We do not know what that "Something" is.
Let's take a chill pill. Oda is notorious for this shit (delivering revelations without explanation as to how its possible)
