I HATE wire fencing. This is exactly why. To me it's just a bad idea. Unfortunately, it's what my entire property is fenced in, the same 5 line high tensile fence just like in that picture. I'm saving up and hoping to replace it, but it wont be in the budget to do so until next spring. My gelding Claymore got his foot through, similar to your pictures, the first day he was here. Thankfully I saw him do it and got him out straight away, with no damage to him at all, but it's still scary. I had two lines of my fence electrified just a few weeks ago to make sure they stay away from it, because Claymore is bad for leaning his head through it to graze, and I live on a fairly busy road. I'm still wanting to replace it all with a rail fence as soon as I can afford it. I HATE wires.
