I think that's a statement about identifiable early genius but not necessarily mature genius, unknown or otherwise.
Anyone can see the same patterns being applied to different problems in repetition with enough time.
That gets boring to those who find no value in tangential rewards. Escaping that with idealism for understanding solely demands more, and I think that's the biggest identifier for lasting genius versus that which is emphemeral / trendy.
It doesn't imply genius but it is indicative of genius recognized beyond youth. Wisdom, common sense - those are either attributed imprecisely or incorrectly.
