My best attempt for now, based on my early understanding.

In go:

• 4 apples 🍏 and 2 oranges 🍊

Out might go:

• 2 green apples 🍏, 2 red apples 🍎 , a banana 🍌 and an orange 🍊

Basically it’s really hard to unpick which fruits are owned by who on the other side and how they were created.

In a regular coinjoin:

• In go 4 apples 🍏 with stickers on of owners
• Out go 4 apples 🍏 with no stickers on
