Magento - Show certain text for two payment methods in transactional email

Question

so what I am trying to do is show certain text for two different payment methods in magento transactional emails. What I have written so far is:

{{if order.getPayment().getMethod()=='payone_advance_payment'}}
    This is A.
{{else}}
{{if1 order.getPayment().getMethod()=='SimpleAdminPayment5'}}
    This is B.
{{else1}}
    If it is neither A or B.
{{/if1}}
{{/if}}

What it does in the email is always show "This is A.". When I use

{{var order.getPayment().getMethod()}}

It shows me the correct payment method I am using but it seems like as if he always thinks that the payment method I am using is payone_advance_payment.

So far I tried everything I know but nothing works. Do you have any idea?
