You had three in your original code, so I assumed that was what you intended.

Something like this?

 or, failing that point me to

I don't know of a description of the <use> element that is complete and 
"reasonable". Chapter 5.6 of the SVG 1.0 Recommendation certainly isn't 
"reasonable" in terms of comprehensibility for many readers.

I have written a couple of short tutorials on the <use> element in Designing 
SVG Web Graphics and in SVG Unleashed but those descriptions are 
introductions to it, making no attempt to be exhaustive.

I hope that helps.
