Quick question on Nationwide RAF

So wife and I have a joint Flexdirect, as well as a joint Flex Account and also individual Flex Accounts funding Flexclusive savers.

Under RAF, could I refer my wife to switch her “main” account from elsewhere (has required monthly pay-in and direct debits) and benefit from the bonus payment? She used to have a Flexdirect in her own name but switched this away from Nationwide almost a year ago)

And thereafter could she recommend me in the same circumstances?

Thanks in anticipation.
