I wanted to understand why the sprouts retract, if the original nerve ending is permanently blocked from Botox?

Botox does not permanently block nerve endings
Retracting nerve sprouts from Botox
You may wish to call Allergan directly and ask for their Consumer Information Department for such an answer.
I am also not a Molecular Biologist but my suspicion is that there is terminal nerve end cell signaling that keeps the nerve and muscle fiber synaptically together.
The nerve itself does not die. It continues to make aceytlcholine in packets which stream down to the terminal end. If no Botox is present, the nerve continues to "work".
I hope this was helpful.
