Not dead. Don’t know why.

Enjoy it. It is on your schedule & everybody else’s though. If you can’t get out of it, get into it.

Now re-do it, but try it with your ass on the seat the whole time. It’ll be fun. You’ll see!

I have same question

You were in a good body position and retained excellent bike-body separation, allowing the bike to move independently and do its thing.

The bike has momentum, it wants to keep moving. And having a strong centered position, allowed it to do that. You can see through the whole sketchy affair that your pedals are level, your weight is evenly distributed, your elbows are slightly bent, but you are in a relaxed position that allows your bike to move. When your nose starts to dive, your weight shifts back.

You didn’t panic and pull brake or do something stupid. You just stayed chill and rode it out. Nice work.
