In that one case it's okay. Reason: * There can only be ONE maxspeed on a road. ever! * What is tagged here is not a given speed-limitation but the fact that the default maxspeed of the country of italy for roads inside cities applies. I don't know anyone who actually evaluates that yet but given the disastrous state of missing city-polygons it may help in speed/time based routing-metrics. However as opposed to city-polygons it does not act as a city-limit to make postal address-searches better. (So you could get a more realistic ETA but get swamped with way too many roads that may be the one you want to navigate when searching for your destination.)
