That's just for automatic funding, so you would send the wire as usual, and then just contact their support and they'd manually credit your account if it doesn't automatically fund. Keep in mind their bank will convert whatever funds you send in to USD, probably at a huge 3% bank rate. It may be cheaper to use XEtrade or Transferwise.com instead, and they probably have their own correspondent banks so no money taken off.
Oh I have already contacted their support and I gathered that they don't understand how international wire transfers work. The support rep kept insisting that I had to send the exact amount they specify as if I could magically alter how the SWIFT system works.
I already have USD so there won't be any currency conversion charges.
