App Store Server API – REFUND_REVERSED timestamp

After a REFUND_REVERSED notification, with no new purchase or renewal, is the transaction’s signedDate in signedTransactionInfo from Get All Subscription Statuses guaranteed to be strictly later than the reversal notification’s outer signedDate? Or can the API return an active subscription with a transaction signedDate equal to or older than the reversal’s timestamp? We’re deciding whether a strictly newer timestamp is a reliable condition for restoring access.
