I don't think there's any precedent for requiring such a supermajority in this case. Actually joining the EU required the support of 0% of the population in a referendum - there was no referendum on joining, the 1975 referendum was merely on whether we should remain in. The same arguments against leaving were made back then too, and if leave had won there'd probably have been exactly the same kind of pressure against following through on it.
