I can say that the system templates in OpenStudio are designed to follow the ASHRAE Appendix G system types. It is no coincidence that the names you see in the OpenStudio UI match the names used in Appendix G (Packaged Rooftop Heat Pump for example). I can't reliably answer the second part and in fact the main reason we have not overtly called the templates out as ASHRAE system types is that the templates will not precisely follow all of the rules appendix G spells out in terms of sizes, fan efficiency etc.
