The lines there don't start at the same point and the faster growth line was crossing the price chart already at the first chart, in the new one this same line is still below the chart now a week later even though the price is the same.
This is a good point. There are always slight variations on how to draw the lines, but the key point is that however you draw it, there has not been a substantial violation of the major uptrend.
Because if the major trend is broken, you see a rapid, crash-type decline with increasing volume. we clearly have not seen that and this is why the longterm uptrend has held.
