I'm the original commenter, and quite simply you're right and I slipped up. It's not really using the terminology correctly for me to say "natural gas is ~75% hydrogen on a molar basis".
Whenever talking about hydrogen's physical properties etc on a molar basis, we'd be talking about H2. So if you had a mole of methane (CH4) we'd say you could make two moles of hydrogen (H2) out of it.
My point was really just that the gas companies' reserves of natural gas mean that they'll do anything to try to stimulate demand for blue/grey hydrogen, because their reserves of natural gas are reserves of hydrogen.
