Why Matlab and Simulink have different Plot for the same modulo function?

Dear community,
as shown in the attached .png, it seems for the same modulo function, the plot from Matlab looks not the same as that from Simulink.
Changing the Solver Settings doesn't make a difference.
Why?

The step size is more important than solver in this case. Reducing the step size to be 1 or 0.5 and making it fixed would resolve the problem.

That's my thought as well. Sometimes the step size is critical in showing what a function truly looks like.
x = 0:10;
plot(x, sinpi(x), 'o-')
Look what happens if we evaluate the function at a few more points.
figure
x2 = 0:0.25:10;
plot(x2, sinpi(x2), 'o-')
Looks a lot more like a sine curve, doesn't it?
