You can invert the output by setting the most significant bit (bit[15]) in the value:

static nrf_pwm_values_individual_t /*const*/ seq_values[] =
{
    10000, 11000 | 0x8000, 0, 0,
};

See the specification.

I want to make high to low pin transition at start point. ie, LED1's sequence is LOW- > HIGH -> LOW -> HIGH, LED2's sequence is HIGH -> LOW -> HIGH -> LOW...

The setup looks correct to me, what is the problem?
