Any reason for the purge tower to have artifacts like this?

The purge tower slice has these odd filament bits sticking out. They tend to curl around things and risk getting back into the print job. Anyone else see this? Normal or a bug?

I dont know why it does that, but my H2D did the same thing the other day with support for PLA new. It started a little before the tower and it drooped down but it worked ok that time. I assumed it was doing that with support material due to adhesion and trying to let it catch on the side of the tower. It was the super slow start of the priming.
