In theory, you're right.  In practice, though, the wanking-about of a
performer with a pitchbend wheel or other device does not move
incrementally.  If it did, using this arrangement, there would be an error
in control accuracy the size of a full lsb that lasted the length of time
between the 2 cc messages.  Still sounds better than 0-127 to my ears,
though, especially when you want to send several discrete messages (as per
a filter "sequence").
