In fact the ECO would most likely not get it in that format. An assistant in the office will likely pull it out and organise it in a fashion that makes it easiest for the ECO to process. I don't think we have heard of a single case of an application being refused for being too organised. Also, I think most US ECOs are used to us neurotic, obsessive compulsive, anxitety riddled applicants.
Making it clear what is what can only help and if you provide too much, they will just ignore it.
