Shows disc priest as shadow

Hi there. I’ve failed in finding the threshhold/logic that decides if you’re ranked as shadow or healer as a priest in classic. It would take me weeks to test a result with trial and error so I hope to get answers here. Yesterday’s raid ranked me shadow on 6/10 fights as healer using power infusion in the start of all fights. Ie: https://classic.warcraftlogs.com/reports/x9h83Krq2RtCXyMN#type=healing&fight=5 I’m the priest called “Vad”. What’s the logic here? Thanks

I’m assuming it’s the same as this?
