There's always some reason for not to write "the perfect" command. Either being in a hurry or you just don't care about it.

Considering the commented out valid code, it looks like he was saving time by just adding another "|" and check the output, instead of improving the existing command and check the output. Something that I do very often as well.

Glancing over this I thought it said: "Either being hungry or...". Nodding in agreement, I then realised my mistake.
