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.
