Once again, it depends on the market. If you mostly are just flying between top 10 markets, then yes, they are mostly only one-way fares. Once you get beyond that, it varies quite a bit. In addition to SFO-MSP/DTW/ATL/PHL/IAH routes mentioned above, here are some other UA non-stop destinations out of SFO with cheaper roundtrip fare filings vs. one-ways -- RNO, OMA, MCI, SAT, IND, PIT, CMH, MSY, RDU, TPA. I'm leaving out many smaller stations without non-stop service that also have cheaper roundtrip fares.
