Is it expected that both "trialPeriod" and "introOfferPeriod" are true in IAP Receipts?

It seems that starting from around 2024-08-20T10:28:00 UTC, both the "trialPeriod" and "introOfferPeriod" fields are set to true in the receipt data of free-trial subscriptions. Before that time only trialPeriod was set to true while introOfferPeriod was false.

Just want to confirm whether this is an expected and permanent change?

Thanks.
