Or, is it more likely that the oil level (being way low) starved those
bearings?       


I'd suspect a clogged passage rather than low oil level.   If the oil got
low enough to starve the bearings it would likely have caused some damage
to the other bearings as well, and the lifters would have gone crazy, loud
enough to have alerted anyone but the most cretin-minded.   Having two rod
bearings fail at the same time suggests that something starved those two
bearings and not the entire engine as would have happened if the oil got so
low that the engine lost oil pressure.     Of course anything is possible
but I'd suspect a clog as the culprit.
