You certainly could be correct: is very remote and there could be few or no local stations, so locations could be off (but it probably states precision on each quake, at least those with focal mechanisms; I have not checked that). But, if these quakes are either on a "detachment fault" or some other non-steep fault, they could be spread out in map view. The fault pattern there that you sent looks complicated, so would not be surprised if quakes are on multiple faults.
