I'm sure he's wrong with that particular phrasing.
If a real problem does arise with a non-working majority perpetually voting to increase their BI, a more flexible answer would be to make the vote conditional on having paid a certain amount of tax, either in that year or over their lifetime to date or some combination of the two. But let's not roll back the clock a few decades on universal suffrage until we're absolutely sure we need to.
EDIT TO ADD: a core principle behind BI is that paid employment is not the only socially valuable form of activity. I believe that. Taking away the vote from people who aren't making a contribution in $$$ form would fly in the face of it.
