Unable to reproduce. Please zip and attach the world.
From what I can see, The repeater in the line with the "broken" redstone torch goes into the last command block. That command block is now strongly powered and powers the redstone dust next to it, which will feed into itself and never turn off.
In short: Your issue isn't the torch, its the repeater.
Works as Intended, or atleast I am 99% sure.
Ah, right you are.
