Banks (especially banks in the same country) can send funds back, that's not the same thing as reversing the transfer. Both SEPA and SWIFT transfers are irreversible. It's even possible to steal money from a central bank by transferring money away with SWIFT. The only real difference is that it's not legal to keep mistakenly sent funds, making irreversible mistakes less likely to happen.
