While I’m confident this is what is shown in OP’s pic, I’d still want support posts under a girder at the edge. Over-build it the first time and be done with it.
That would explain the use of 2x12 (2x10 maybe?) lumber and how it kinda disappears into the house past the siding. Still, I wouldn’t want that lumber exposed to the elements like that - it’s like asking for moisture to penetrate the structure.
Also: no ledger board on the house side of that deck. Even with proper post support, it’s still a widowmaker.
No leger board is a good thing in this case, probably means it’s built as a cantilever setup like this
And the tiny supports probably aren’t needed at all and they just made a funny photo.
Edit: i have no idea if that far of a span is appropriate for that type of cantilever.

Yeah, the bare wood is certainly a choice if that carries through into the house.
