I agree with you, the code isn’t as readable as it could be. But that’s precisely the point here: it’s an exercise in artistic license, so its conciseness is a feature, not a bug. Think of it like poetry.
I can recognize why it will generates a feeling of elegance, as some say with short mathematical concise formula. However this is more like of esoteric practices: it's meaningful for the selected few that went through the initiation, and has only the charming/frustrating taste of mystery for other.
But, at least to me, it's nothing like poetry. Anyone, without any specific formation, can read poetry and understand something of it. In poetry, artistic license is the exception, not the general rule. The deep meanings, intertwines between form and content, the attention to metre, the use of allegories, and so on, will not be consciously grabbed by every reader. But still anyone that has the base language knowledge required can read it and find some sense to it.
