No, not quite right
If you purchased an already released game, it will be proceed immediately, there must be something wrong with your PayPal,
I thought Origin does not accept PayPal? because I don't see PayPal method selection.
Normally only if you pre-purchased a game that is not released yet, you will still receive confirmation email, the deal will not be proceed and not charged, until the game is being released.
Placed order payment will go through at the time when the game is released. On Origin, you "pre-ordered" a game without placing deposit or full payment, only pay when the game is available, unlike Steam, you pay full first when you are pre-purchasing a game.
The only thing I don't like Origin does this is they forced you to let them have your Credit Card/ Debit Card info for automatically charged you at the game released time.
For the special offers such as Christmas Sale, they offered unreleased games at discounted price, I believe if you pre-purchase them, you will be charged the discounted price at the game release time.
