Back in BFA, I transferred my hunter Moltun from Bladefist to Area 52, and again about 6 months ago to Zul’jin.
If I try looking my name up on the armory it shows up with it’s old gear on bladefist and the current character on Zul’jin as well, even though they are technically the same character: https://worldofwarcraft.blizzard.com/en-us/search?q=moltun
I know the armory takes time to update sometimes but this transfer happened years ago.
