I don't know the internals of the Hardware Simulator so I can't really answer this. Figure 3.5 is correct. If you look closely enough you will see that the edges of the reset, load and inc are slightly to the right of the clock falling edges.  It would be better if these were offset a bit more so that it was easier to see.

The  square wave clock as drawn in figure 3.5 is a hardware detail that isn't really required. The clock could be a series of narrow pulses, or some other hardware implementation.

What's important is to understand that the clock is a periodic event. When a clock event occurs the state of the inputs determines the new output state.
