The article states "Around midnight, it will be directly overhead." This depends where you are, and it will not be true for most humanoids. From Washington, DC, for instance, it will be 45 degrees up from the horizon at midnight: http://www.wolframalpha.com/input/?i=jupiter+sky+position+fr...
If it's directly overhead on midnight (over the equator), it must be a Sun-Earth-Jupiter alignment, which makes sense as it is the closest distance between both planets in the Earth year.

From Oslo, Norway, a little under 9 degrees: http://www.wolframalpha.com/input/?i=jupiter+sky+position+fr...
