Most everyone I know including myself carry the saw over their shoulder, sometimes I wear a pad on my suspenders sometimes I don't. Out of logging for over 13 years I have yet to seriously injure myself packing a saw that way with the bar in front of me. I have packed alot worse things on my shoulder like 100+lbs of riggin blocks, spiked tree plates and etc all on steep and brushy ground. My advice would be don't trip and fall, if You feel like you might fall simply toss the saw away from You with the hand touching the end of the bar. If You don't feel comfortable about it or have concerns of being hurt don't pack it that way. I don't mean to sound rude but You might just have to practice and practice til You figure out how to get a saw on You're shoulder.
