Many modern fenders only have the one tie wire. you really don't need much fender forward of the fork, so many are designed short and not stayed. I use double attachment points at the fork, front and back of the crown to attach short fenders. I am speaking of the tabs that attach the fenders, not the wires/ties/stays in the photo. This allows me to dictate some rake ahead of the crown.
Of course if you have the room and the fittings, more points of attachment are better. I also run the tie wires to my rack if I install a front rack.
