Your problem is related to the way Plot selects points in the plot
interval selected for evaluating your function. You can obtain the
desired result by changing the PlotPoints option or the MaxBend option.
The following Plot commands give 7 fixed points in the interval {0,1}

Plot[{sf[sf[sf[sf[x]]]], x}, {x, 0, 1}, MaxBend -> 2]

Plot[{sf[sf[sf[sf[x]]]], x}, {x, 0, 1}, PlotPoints -> 50]

Cheers, Bri
