...but different samples of the same dataset, surely?
"Banik et al. only consider binaries with separations >2000 AU. Those are already quite close to the MOND regime, i.e. a0. You expect to find a change in behavior for different separations, i.e. once you approach the MOND regime, which they do not see.
"Chae additionally considers tighter binaries than Banik, which must be in the Newtonian regime even in MOND (a>>a0). He uses these to calibrate his analysis, since he knows what Newton should do. He finds that MOND behaviors begins at 2000 AU!
"Right where Banik's sample starts."
He then goes on to mention a third sample which excludes triple systems.
