Gas valve flare end conncetion?

I'm installing a new water heater and need to install a gas shutoff valve (with flare end) connected to flexible gas line.

The flex line instructions say:
Do not use Teflon tape or pipe sealant on any flare ends because you will not

obtain a leak-free seal.
Keep flare end of fitting free of grease, oil and thread sealant.

I just want to double check that means no dope on the flare end threads too, not just the flare itself, correct?

And I assume that's because the flex tube is compressed to the valve flare for a tight seal - no need for thread sealant.

That is correct. The flare with make a seal. Tape or dope will only interfere with that seal.
