Apparently it's because the last season ended on a very intense and long-running arc (the yor cruise arc) and the chappys that followed were more of a cool-down, catch up with side characters, set. So jumping back in in the chronology was going to be filler unless they went very out of order. The family portion was also anime original, which was just done to reintroduce the whole family for the season. It felt sloppy imo and I don't think it was a particularly strong episode, but I'm hopeful for the rest of the season as I have been very satisfied with the show as a whole up until now
