The question is about falling asleep, rather than waking up early right? Waking up early is simply a question of alarms/light/whatever.
Eating early will have no measurable impact on the ability to "wind down" and sleep as far as I can see, nor does that link seem to support it?
I can pretty much always sleep (I'm lucky) and I go to bed late (I'm dumb and play too much dota) - so I struggle with the waking up thing. This is despite not really eating in the evenings. Anecdotally I'm just saying I don't think there's one most important thing - just a set of factors and decisions which have an impact.
