If there's no flag indicating DST. America/New_York is the timezone designation. Part of what makes TZ discussions incredibly difficult is that people play fast and loose with the terminology. I think the person you're responding to is simply saying that if you made the meeting in a non-DST observing zone, the meeting time would still wobble in a DST-observing zone. (I'm not sure why they're noting it, because my comment also clearly spells that out, too, albeit in reverse. But yes, it works both ways.)
