I would say it has better airflow when Flat so if this is directly related to RROD then I would say Yes it is more likely to fail if run upright, Including the risk of disc scratching I can't see the space being saved being worth the risk whether it's a fact or not.
Having re read that I am mental as it would have better airflow upright
I don't care mine is only run flat
