No, you were right the first time. 60Hz 'switches direction' 120 per second. The first quarter phase is up, then from the + peak to the - peak(2nd and 3rd quarter phase) it is going down(1st change), then from the - peak back to 0deg it is again going up. Or, if started from 90deg at plus peak, one could say it crosses the zero phase line twice.
