The name uddiyana is explained: the lock is so named because by it the breath uddiyate, "flies up." The verb ud-di means "to fly up, to soar"; from it comes uddiyana, "flight." And the technique is named for what is felt when performing it: the drawn-in belly creates a sensation as though the internal organs are going upward.
Worth noting is the precision of the instruction as to when to do it: kumbhaka-ante rechaka-adau, "at the end of the holding, at the start of the exhale." This detail is technical and important. Drawing in the belly with full lungs is harmful; it is done on empty lungs or during exhalation. And that the book states this shows it was written by someone who did it himself, not one who merely repeated hearsay.
A general rule follows from this, useful beyond yoga too. A sound instruction always says exactly when; an instruction saying only "what" is usually incomplete and therefore dangerous. "Draw in the belly," without "on the exhale," is harmful advice, not half of a useful one.
The Vaishnava side speaks in her guides of timing just as precisely: when to rise, when to sing, when to eat, until what hour not to sleep. From outside this looks like triviality; in fact it is the same thing: an instruction without a time is not carried out.
