Absolutely so. I've seen this policy many times and it always results in less vacation around. Not only that but in his very post linked to he makes clear that he considers a proper 6 week vacation (I take off August like most civilized people do, and I take off a bit more at other times) is unacceptable because they are tracking a metric called "pace" that proper vacations would interfere with. He then suggests that what they really prefer is that you work at least half time (possibly this is 8 hrs a day instead of 16?) remotely from wherever you are taking your "vacation". Um, that's not a vacation. Vacation is no contact whatsoever with work, otherwise you are not recharging at all. There is no such thing as vacationing half time. That is working half time, not vacationing.
