While the aviation agency's Wallops Flight Facility is pleased that the balloon made a near-circumnavigation in its 32 days aloft, the mission was originally planned to last 100 days. “Controllers detected a leak developing in …
Judging by the track, not really anything close to an unqualified circumnavigation. A near circumnavigation of the Antarctic continent is more accurate with the qualifier. If someone at the South Pole dances around the actual Pole, would that also be a circumnavigation? Qualifiers help to disambiguate.
Still, it's all good science and engineering, especially getting the balloon to maintain shape and altitude despite changes in temperature, even if the reporting is ambiguous.
