Anthony,

This is precisely the situation where breaking right might result in a collision. Flarm display/alarm is not sufficiently accurate to determine if an indicated "head-on" is actually straight ahead or several degrees left or right (or above/below).  Rely solely on look-out in terms of taking avoidance action.
