The block diagram shown in the figure is used to implement a backward difference integrator in a numerically controlled oscillator nco of a phase locked loop pll. Simulink detects instances such as these ie. When you move this feedback signal to the front of the first integrator block you should modify the feedback signal properly so that the two configurations produce exactly the same signals.
The integrator block outputs the value of the integral of its input signal with respect to time.
Therefore label the new feedback signal as ys s more generally ysh1s where h1s1s. Create your block diagram to identify the most important components. In this instrument the frequency is controlled by varying the magnitude of the current that drives the integrator.
