Don't understand

How can received Bitcoins be from multiple addresses?

Sender has 0BTC,
he receives 1BTC on address ABC and 2BTC on address DEF,
when sending 3BTC your way, you will receive coins from both of his addresses ABC+DEF to your address.

That's how.

Surprisingly enough that makes sense to me. Now I think I understand. Thank you.
