I have a question ....
Is AR2209 and H4350 the same powder?

What I know is Hogdon 4350 is manufactured by ADI/Thales and the listed burn rates are shown as similar.
Does Hogdon have their own recipe that ADI/Thales concocts for them?

Yes, it's rebranded for the US/International market.

It's a hell of a minefield, IMR (DuPont) sold out to Hogdon in 2003 and ADI make powder for Hogdon.
Reloader 17 is a great powder and no longer for available in Australia for pushing 200g+ projectiles out of a 308W up to 1500 yards.
Supposedly, Reloader 17, AR2209, N550 and H4350 are similar and in reality from my experiences the former three aren't comparable.

In my experience if your researching a new-to-you cartridge and you see a common load charge for H4350 or Varget, then the same charge with ADI2209 or ADI2208 performs as well.
With minor 0.1gn tweaks you can find a load/desired MV very quickly for your barrel.
Aussies talk ADI 220....
US guys talk Varget, H4350, etc
