Figure 9.1 does not match with example 9.3

Hi,

Figure 9.1 show a Tessellation Quad based on the example given in Example 9.3.
The Example states
gl_TessLevelOuter[0] = 2.0;
gl_TessLevelOuter[1] = 3.0;
gl_TessLevelOuter[2] = 2.0;
gl_TessLevelOuter[3] = 5.0;

While the example states that gl_TessLevelOuter[3] is 5, based on the image it should be equal to 4.0.
