That is just for Directions, and there appears to be an issue right now as it used to update more regularly. Your edits will appear on the map right away, but Directions will continue to follow the old roads/conditions until the next time it is updated.
There is no sync with other products.
Maps updates "instantly" (usually before you can check, very occasionally might take up to a day) with Map Maker changes. Other products such as Mobile, Search, Earth and Directions then render the changes over time. For all of those we used to say between 2 and 8 weeks depending when in the cycle you did your update, but lately Directions is taking longer.
You would be better off to use Maps for you GIS needs; or if using Earth you should draw in or flag any changes.
