Usually this advice is given to those that are clearly not eating enough calories to sustain their basal metabolism, let alone any activity and are reporting that their weight loss has stalled. While doing this once in a while isn't going to make much difference (most of us have a low cal day once a while where we just aren't hungry and don't want to eat), doing it for a prolonged period of time in the hopes of speeding up weight loss is utlimately self-defeating.
When the body senses that caloric intake is consistantly below that needed to sustain basal metabolic activity (breathing, cell replication/repair, digestion, heart beating, brain activity, etc...), it begins to lower your metabolism to compensate to protect you and help you survive the famine that it believes has begun and weight loss slows or stops. You would then need to lower caloric intake further to continue weight loss and the process repeats itself. How long it takes for this self-preservation mechanism to kick in varies from person to person, but eventually it does happen if calories are restricted too low for long enough and yes, there comes a point where calories are so low that it overrides this protective mechanism, but do you really want to go there? I've seen many posts from people who were eating too little and had stopped losing only to see weight loss resume again once their caloric intake was increased to a level that could at least support basal metabolism. What level is that? Generally, it's accepted that your basal metabolism is roughly 10x your current weight (check some online websites on calculating basal metabolism if you want to see exactly how this is calculated). Now granted this formula may not apply if you are very overweight, but for the majority of people it applies. What I see a lot of people doing is using the 10x current weight as their max level of calories for the day to keep losing and 10x goal weight as their minimum and that's the range that they shoot to stay within which seems a reasonable approach to me; it's one that I use myself.
OTOH, lots of people don't pay any attention to calories at all and simply eat when hungry and enough to feel satisfied and they do well with that. I'd only recommend taking a closer look at your daily calorie levels if you aren't losing and have ruled out other possible stallers OR if it seems like the poster is consistantly undereating/overeating; otherwise why stress about it?

Exactly. Ketosis is a natural appetite suppressant; sometimes a too-effective one and some people don't eat enough simply because they aren't hungry.
