   Why does BGP pick only one route when it has several options? 

90% historical reasons.

In the general case, it was very difficult with BGP3 to select multiple
paths and not lie about the AS path.  Such lies have the obvious bad
consequence.  ;-(

More sophisticated behavior is obviously possible.   But requires more CPU
cycles.  ;-)
