Understanding Transactions on Blockchain

I randomly grabbed this address for illustration purposes: 1Ey46cTVUPqogpfNEHLQpz3B7FFfgmQvkG

It held 7.25 BTC. Let's assume the owner sent 2.30 BTC to Person B. So his "change" address gets 4.95. In the example here, the change address is the same address that initially sent the funds: (1Ey46c...):https://imgur.com/a/wvNp8oD

​

In this second example here, the owner holds 0.36 BTC in this address: bc1q0wm965qp74rszle9patvrgrsp4k6f2ey0n9fwc

He sends 0.24 BTC to bc1q2... and the change address gets 0.12.

What confuses me is that the change address (bc1q2q4...) is a new address in this example:

Why is this handled differently?

And can the sender in the second example now receive BTC to 2 different addresses (bc1q0wm... and bc1q2q4...)?
