Essentially being 35% Levantine, 45% Southern European (Italian and Greek, some Iberian in there also), and 20% Northern Euroepan (simplifying a little) is superficially similar to Italians in ORCHESTRA because of the deeply divergent ancestries these groups have when blended together looks, with regard to a tool only made for recent ancestry, close to Italian.

It is overestimating how much is actually Italian here. Other Jewish groups don't have that extra Northern Euroepan ancestry, so it doesn't push their deep ancestry components to that of Italians, so it doesn't pick it up at all despite other studies showing that all Mediterranean Jews have it
