A first glance at this sequence might tell you that it is very difficult.  However, it is not.  Let's break it down.  The entire
ascending pattern is based around the figure below.  The first 3 notes go right up the B Lydian scale and are followed
by a 6 note pattern on the 5th string.  The pattern goes back down the scale and repeats itself.  Try this out a few times
until you can play it starting on any fret of the 6th string.  Like with the first legato lesson, no notes are picked, and
watch your muting.
Now try the entire sequence.  The descending version is a combination of the 6 note sequence on 5th string of the
above example and a bunch of strait up and down patterns.  Try to find out the pattern yourself.  I'm sure you'll have
much more success decoding the sequence yourself than if I try to describe it in any more detail than I already have.  
Be sure to warm up before attempting this at high speeds.
As with the other examples, I encourage you to take this basic idea and expand it to include your style.  Try using
different scales, playing in all keys, just playing on the middle strings, just playing the idea on the top and bottom strings
only, etc, etc....
