It's probably more that communication between different cultures and across a 11.5 hour timezone delay pose a significant barrier that require efficient project leadership and company culture to manage.
Neither of these exist in a relatively local WFH setup. People still have the same weather, sports and other interests which allow for better cohesion. Hell, I'd often zoom into a meeting rather than walk to the conf room pre-covid anyway because I'd gain 5m to/from and I had back to back meetings.
