A very important reason for the percussion vlef not to behave like the 
trebble clef is that the percussion clef is often used on staves with 
another number of stafflines than five.
The middle line (or middle space in case of even number of staff lines) 
is used as a reference point, meaning that if you change the number of 
staff lines, then notes that used to appear on the middle line will stay 
on the middle line. On a 3 line staff, for instance, the trebble clef 
will appear on the lower-most line, så that b' is still on the center line.
