This graph interchanges the axes compared to the cited websites, that's all.
In general, to read a probability plot, ask yourself "what changes in the data would be required to line the points up diagonally?" In this case, the data are shown on the x-axis, so changing the data would slide points horizontally along the x-axis while retaining their vertical positions. To get the points into a diagonal line we would have to slide the largest (rightmost) times to the left (that is, pull them in towards their middle) and we would have to slide the smallest (leftmost) times a little to the left as well (that is, push them away from the middle time value). That tells us the large times are too big compared to a normal distribution: they are skewed towards large values (considered the "right," no matter how the plot is drawn; better terminology is "positively skewed"). (For reading q-q plots in general, I have posted a more elaborate explanation with illustrations.)
When the axes are reversed, the times (or, generally, the data) are plotted vertically and the sliding has to happen in the vertical direction. There's no chance of confusion, though--provided the axes are clearly labeled!
