I've only made a couple starters, but what's wrong with having a high OG? The same amount of sugar will be in the solution no matter what, right?
Ideally, the starter should be at or slightly below the gravity of the eventual beer you'll pitch it in. I go about 1 lb DME per 1 gal water: that gets you about a 1.045 wort.

I'm confussed too. I always use 500ml of water and .5oz of DME for a starter and never have a problem.
