The unspoken thing here is that the oil filter bypass does let oil past in some operating conditions. Despite being called a "full flow" filter, it doesn't always filter 100% of the oil - and the filter medium itself isn't perfect. Getting contamination out of the engine is the only guaranteed way that it won't get stuck in your bearings.
