No, it is not separate. Rebar gets bent down and tied into the decking. This is exactly how it’s done on houses. If they did not tie the decking into the shell the decking would sink where it meets the coping.
Its almost self explanatory if you just think about it (not trying to be rude, but it should be common sense). When they pour concrete decks onto the house they tie the rebar into the slab for the exact same reason, then the opposite side will have a footing like a traditional monolithic slab. This is the correct way to do it.
Here’s a picture of what it will look like, you can see the shell rebar bent 90 degrees and tied into the deck rebar.
