I don't know if Trello still works this way after the spinoff from Fog Creek and subsequent Atlassian acquisition, but I visited Trello's NYC office and they had a similar setup to Fog Creek's. Trello also has a significant number of remote employees.
Trello shared an office with Fog Creek until last December or so, so no surprise that they're similar. I suspect Trello retained the offices layout since Fog Creek was the one that moved out.
