I interpret this the same way Jerry did. In the first statement you admit that multiple attackers was a situation you were not prepared to deal with. In the second, you use the fact that you didn't fare too well to support your claim that the aforementioned strategies have no value. However, this doesn't really make that great of an argument because you admitted that you weren't prepared to deal with this type of situation. If you had trained in multiple attacker strategies would it have made a difference? Maybe, and maybe not, but to dismiss these strategies out of hand because you were not able to employ them doesn't make much sense.
Before you get ticked, let me say that I'm not trying to attack you personally. Anyone that is confronted with a situation for which they have not trained is not going to be able to respond with the same level of skill that they would display had they trained for situations of that type. For example, a fighter who only trains stand-up striking isn't going to fare too well when rolling around on the floor with a BJJ player. A guy that trains nothing but TKD point-style fighting probably isn't going to fare too well in a brawl at the local bar. Does this mean that the training these guys have is of no value? No, it means that you should train in such a way as to include elements from all the different ranges of combat and as many scenarios as possible (larger attacker, armed attacker, armed defender, multiple attackers, etc.).
I'm a big fan of shoe-fu when it comes to dealing with multiple attackers. However, what if you aren't in a good position to escape? You may have to fight and survive long enough to create the opening you need to get away and that is where these strategies become valuable.
