1) You are absolutely right, whitespaces are not allowed in id and name tokens.
2) Text node doesn't have to be unique, id token does. For example,

<h1 id="heading-1">Heading</h1>
<h1 id="heading-2">Heading</h1>

is fine, while

<h1 id="heading">First heading</h1>
<h1 id="heading">Second heading</h1>

is not.

And finally... let's take a look at the snippet in question:

snippet h1
<h1 id="${1:heading}">${2:$1}</h1>

You type h1<TAB> and you'll get <h1 id="heading">heading</h1>. Cursor at the first tabstop and id value is highlighted and ready to be replaced. Now you type a new value (it should not, actually must not, contain spaces; but no one is forcing you to type spaces here), this value is also used as a placeholder for next and final tabstop. You hit <TAB>, cursor moves to the second tabstop (element's text node), text is again highlighted and ready to be replaced. You type a new heading.

Personally, I see no value in using the first variable as a placeholder for the second (for header tags anyway). I much more prefer the way it's done in this snippet file (it also has a final tabstop outside the closing tag):
