Premature conclusion. Even if it was the same failure mode, one needs to establish if the upgrade improved the reliability or expected time-between-failures and thus made it unlikely that a dual engine failure were to occur in the lifetime of the B787 RR fleet.
Nobody should expect perfections (no failures) but of course the corrective action were expected to significantly lower the risk of no duals
