The second requirement for an upward trend line is that the prices move upwards from the low reversal, and make a new high. The new high will not be part of the actual trend line, but it is the beginning of the upward price movement (the trend). If the new high is not made, then the prices are not starting an upward trend, and may move sideways instead. The upward price movement and new high are shown by the yellow arrow in the example chart.
