Howard; I think the diagram is OK.

Assuming the pilot and load are synchronized, then let’s put the right turn signal ON and analyze the circuit when the Orange wire is ‘hot’. Both the Orange and Pink are ‘hot’ resulting in zero voltage drop across the left indicator . . . that is when the right turn signal is ON, the left indicator is not producing light. That seems correct so far.

With the Pink wire still ‘hot’ the right indicator will be powered, and have a ground path through the Left turn signal bulb. Since incandescent bulbs have less resistance when cold this ground path is sufficient to provide enough voltage drop across the right indicator to produce light. Seems that’s correct also.
