Setting a supplier to be any currency means that the supplier can trade in any currencies which exist in your database.
When selecting an any currency supplier for any transaction, the default currency is pulled through, this is the VAT type that you've set on your supplier.
If you've set a home VAT type on a supplier, and your home currency is GBP, then GBP pulls through as the default currency on transactions, but the currency field is enabled for you to select the currency you wish to perform the transaction for the selected supplier.
