You are correct - that's what is happening. But the correct current draw (as far as the LKM is concerned) is only used to monitor bulb status. The voltage to the bulbs is still (as you say) a form of AC and this will cause the LEDS to flicker. A capacitor with smooth this "AC" (PWM actually) to a DC-like power supply and the LEDS operate correctly.
What I'm guessing at is why the resistor has a similar smoothing effect!
