Nope. His duty is to test me to the PPL standards, no more, no less.
The DPE has significant latitude to fail candidates.

Special Emphasis Areas
Examiners shall place special emphasis upon areas of aircraft
operations considered critical to flight safety. Among these are:
1. Positive aircraft control,
2. Positive exchange of the flight controls procedure,
3. Stall/spin awareness,
4. Collision avoidance,
5. Wake turbulence avoidance,
6. LAHSO,
7. Runway incursion avoidance,
8. CFIT,
9. ADM and risk management,
10. Wire strike avoidance,
11. Checklist usage,
12. Temporary flight restrictions (TFRs),
13. Special use airspace (SUA),
14. Aviation security,
15. Single-Pilot Resource Management (SRM), and
16. Other areas deemed appropriate to any phase of the
practical test.
A given special emphasis area may not be specifically addressed
under a given Task. All areas are essential to flight and will be
evaluated during the practice test.
Aeronautical Decision-Making
References: FAA-H-8083-15, FAA-H-8083-25; AC 60-22.
Objective: To determine that the applicant exhibits sound
aeronautical decision-making during the planning and
execution of the planned flight. The applicant should:
1. Use a sound decision-making process, such as the
DECIDE model, 3P model, or similar process when making
critical decisions that will have an effect on the outcome of
the flight. The applicant should be able to explain the
factors and alternative courses of action that were
considered while making the decision.
2. Recognize and explain any hazardous attitudes that may
have influenced any decision.
3. Decide and execute an appropriate course of action to
properly handle any situation that arises that may cause a
change in the original flight plan in such a way that leads to
a safe and successful conclusion of the flight.
4. Explain how the elements of risk management, CFIT
awareness, overall situational awareness, use of
automation, and task management influenced the decisions
made and the resulting course of action
