That stops it from reaching a "false" consensus, but makes it easier to stalemate the network. With a 60% consensus, 41% can deadlock the network. A deadlock of a financial transaction system is de facto control (if we believe Dune). With a 50% consensus, 51% can deadlock the network, but have no need to, as they're already capable of voting their agenda in. Any increase of consensus past 50% gives an increasingly small minority group the power to deadlock the network. Further, 50% is the magic point at which a minority can neither overrule a majority on consensus nor deadlock the network. Deviation from that middle increases one of those two failure modes.
