I thought B meant without the current limiter?
It's possible that the Widlar current source is effectively optimized for a single current or close range of currents.
There is no "out of compliance" indicator like there usually is on a typical CC supply. This might be a voltage comparitor looking at the rail vs, the drop across the current regulator.
