Really I think it's just applied poetry. The rational argument associated with the point is boring. Parsing out "envelope of serendipity" might take epsilon more time/effort but it's that epsilon which causes you to feel a small spark of discovery WHILE parsing the sentence. That feeling of discovery convolves with the conceptual meaning of the sentence and immediately you mentally associate with the similar spark-like feeling of serendipity, and probably also remember a couple of times things like this HAVE happened at parties too. It seems pretty elegant to me. Perhaps it is a rhetorical trick but it's also good people-hacking.
