Looks like someone needs a lesson in saftey wire applications.
I wish I had a dollar for every safety wire I attached in all those years as an aircraft mech.
Personally I would not use the single strand continous loop method, even if the book shows it done that way. All it takes is for the wire to break, and all the fasteners security is jeopardized. Even that saftey on the upper right should be done with the double twist method.. The pulling tension of the wire should go up and over the bolt head, and it will provide better tension and reliability. Take the wire over the bolt head and twist the wire CW making 6 to 8 twists per inch, go into the next bolt head in the hole that makes the greatest angle, twist again but this time CCW and continue on to the next fastener, this time tewisting CW. When finishing up the pigtail twist until the wires just start to get snug, and then using wrist action, go in a circle without twisting, sort of like flipping your wrist. This will draw up the wire very snug into the fastener. Cut the pigtail about 5/8" or 3 to 5 twists long, and double it over and tuck out of the way. When applying safety wire you ned to keep from nicking or kinking the wire, as this makes it prone to breaking.
A wire twisted as that one in the upper right, with it being single strand and twisted between fasteners IMHO is just a matter of time until it breaks as its impossible to keep it taught that way.
See attached file for example of proper saftey wire application.
