You kind of have to count back from where the next repeat starts to know where to start after the decrease.
If you're working from a chart, you can mark the chart to show where you decreased, or if you're working from a written pattern, copy the directions and cross off the stitches you eliminated.
If the first stitch after some of the decreases should be a yo, just eliminate it and count that as your decrease.
