Before revision:  We explicitly demonstrate these ideas for the toy model of two TFs competing for the same binding site. We suggest that this mechanism potentially explains the motif of a coherent feed-forward loop terminating in overlapping binding sites commonly found in developmental networks , and discuss three specific examples.
