Google: Here's something weird. The tail (or hair) of the comet, usually point away from the Sun because it is a projection due to the ice evaporated driven by the solar wind. It is what is shown in the frames.

I noted that, it may be something to do with the viewing perspective, SOHO is in a somewhat similar plane to that of the Earth whereas the orbit of the Comet is somewhat angled to the solar ecliptic (image from http://www.solarsystemscope.com/ison/. Just guessing here but maybe the explanation.
