No, I don't think it automatically creates an ecash token. However as an introduction to a new app like cashu.me takes some getting used to, and will probably involve some messing around, you can create an ecash token without being conscious about it, and as soon as a token is created its value will be deducted from your balance, which can be quite confusing. I think something like that happened
I was playing around more with this today. I created a token to send 100 sats and I saw that it immediately deducted it from my balance. I then deleted the token thinking that it would just add it back to my balance but instead it appears to be gone for good. The correct action would have been to receive it back. It seems like deleting it should automatically receive it back to my balance. So I'm not sure if this is a design flaw or if I just have to learn a new way of doing things.
