The articles are about two subtly different problems. The first is finding something difficult in your code and then getting distracted learning about it in depth. The second is about getting lost in the process applying deep theory to a simple concept. The first is "I know too little, I must know more", while the second is "I know all this cool theory, I must use it."

I think both could probably be called bikeshedding, but it's interesting to make a distinction between the two.
