The writer is writing playful English. It is not straightforward. He is saying simple things in a complicated way for the fun of it.
Suppose my wife sends me to the store to get hot dogs and buns, I come back with a package of 8 hot dogs and a package of only 6 buns. She points out my mistake.
I could say "Oh, I'm sorry."
I could say "I guess I didn't do a good job of food purchasing."
I could say "I guess I shouldn't apply for the position of Assistant Secretary of Hot-Dog-and-Bun Supply Chain Coordination and Synchronization to the Assistant Governor."
