Is ADuCM355 Datasheet's Figure 2 wrong?

According to the ADuCM355 Datasheet's Figure 2, DE0 PIN and DE1 PIN have to go through HSTIA to reach ADC MUX.

However, in the Table 63 of ADuCM355 Hardware Reference Manual, MUXSELP can skip HSTIA to select DE0 directly, which looks different from DataSheet Figure 2, is Datasheet's Figure 2 wrong?
