Yes, and that it's 100% business. Hard to get a good social conversation in a remote meeting with 5+ people, so the real meeting starts right away, and when it's done everyone disconnect. Compared to a physical meeting where people will talk in smaller groups before and after.
It's a cultural choice. In my team, standup takes 30 minutes because we spend the first 20 chit-chatting. It may seem like a waste of time but honestly it's a great mental kick-off for the day.
