The system doesn't eat ACARS. This quote is to explain a possible delay in the time stampings, but not a message disapearance.
If the statellite link is lost, ACARS in the pipe are kept until the link is restablished. The protocole takes 6s with full aknowledgments at both end.
As the satellite was obviously working until 02:14:26 with no ACARS processing interrupted up to this point (it is known from the Sat operator), only very late ACARS in the maintenance system (not already processed) was kept by it until the end of transmissions.
