True to a certain extent. You must be aware that you cannot directly the OGR 
OSM driver in QGIS if there are more than 100 000 nodes, ways or relations in 
the file (small extracts will work, but possibly with not great performance). 
Above that limit, the file must be processed with ogr2ogr, which will use a 
specific mode to drive the OGR OSM driver ("interleaved" mode), that QGIS 
doesn't use.
