Okay, let me tell you several things that are wrong in this post:
1. There is no "guideline" for us to follow that specifies how long we should ban someone. Whoever told you that the regular time for banning someone for recent punishments is 3 days is just simply wrong.
2. Staff are not allowed to punish themselves or others for any rules broken. As stated by Sorle, you should make a post on the forums or approach a Lead Team member such as myself on Steam. You can add me if you want to, but you will need proof of Sorle RDMing if you want him to be demoted.

Other than that I do not see how Sorle could have done anything wrong. Or at the very least, the things you describe in this post (aside from Sorle RDMing, if that's true) do not show any mistake made by Sorle.
