Strange things about hotspotting after latest update

I noticed that if you are connected to wifi, instead if disconnecting wifi when you turn the hotspot on, you can now hotspot your wifi back out. Perfect if you have to pay to connect to wifi. Means you can share that wifi connection.

I also noticed that if you connect to wifi and activate the hotspot, wifi calling and SMS operate as if you are connected to a cell Network. I had expected wifi calling to work when wifi calling is active, but for some reason, you can also send SMSs ONLY when the hotspot is on.

I cant figure out why either if these two fantastic things work only when the hotspot is on. What is the connection?

It means that if you are somewhere where there is only wifi (and obviously no cell service), you can hotspot to all your devices from your phone, take calls and send SMS. That's something new since the update.
