Can someone or whirlwind please respond on this part from my review-

I don't know if this is intentional from whirlwind or not. Here's my mixing-
1. my addy to WHIRLWIND1 address
2. WHIRLWIND1 sent BTC to their X address
3. And sent me BTC to my desired address from address X (same address from the 2nd step)

Again,
1. Used Notes- sent BTC from my address to WHIRLWIND2 address.
2. WHIRLWIND2 sent BTC to X (same as previous)
3. When I withdrew, they again sent me BTC from address X
Does it work this way? I don't think so. Basically, it's like MY btc to whirlwind and the same BTC is being sent to me.
I felt like I was sent my BTC.

I'm not a guy who used a mixer a lot of time. I used it mostly just to check out how it works. I have tested a few mixers including ChipMixer and all of those were to get an experience of how the process work in individual site.
May I know what I'm missing? My bad if this is a very much stupid question I had though I think it wasn't.
