Does change of carriage count as transfer (and extra travel day)?

Hi! I have a Global Flexi Pass and have made a reservation for a Snälltaget night train from Hamburg (23:59) to Stockholm (14:19). Although this is a direct train and I ordered my reservation as such, the ticket I received includes a change of carriage in Malmö (where some carriages are swapped for others). Does this count as a transfer for my pass?

I hope it doesn't, as I planned to only use one travel day for this journey (the day of departure from Hamburg). An official transfer past midnight would require me to spend an extra Interrail day, which I do not have available.
