I've found that there are certain types of engineers who take the chance to hijack a shared whiteboard situation in order to publicly display their solo thought process. Seems like maybe an ego thing or at the very least a mildly autistic inability to share the board and collaborate. Just like pair programming, whiteboards can work really well for certain personality matches or really poorly for others.
