As far as I can tell train=yes is an access tag https://wiki.openstreetmap.org/wiki/Key:access saying trains are allowed, which seems implied by railway=station. Do you have any other references which explain what the train=yes tag is for and what it implies in this case?
I agree wheelchair=yes on the station is quite broad, certainly the detailed indoor footway mapping which exists at central goes much further to document exactly what the wheelchair access is. At the high level I think it's fair to assume that at the top level it just means that the station and all its platforms is accessible via wheelchair, which I think it is. It can be useful for people consuming OSM data to at a glance see which stations are wheelchair accessible and not. Sydney Terminal, I believe, is only used for the country train services. In this context it's still referring to the train station, and not the platform but I think you could make an argument either way. The boundary shouldn't be theoretical, per OSM the boundary should be from the rail perspective where the entry/exit signals are, with the public_transport tag mapping the station from the passengers perspective. I'm not sure how anyone would know this without being an actual train driver or with insider knowledge. iD warnings might need fixing in this case, but I haven't looked at them in detail so I'm not sure.
