At the end of a 16hr tour of duty a long, familiar, briefed, and loaded arrival and approach would be a safer course of action. Especially if their touchdown fuel was showing just under what they legally required.
They would have been using Flaps 20 instead of the normal 25 or 30 with the associated extra landing distance required, as per the low fuel checklist and any extra fuel used by doing what they did would be better than a possible go around. Simple Risk mitigation.
