Symmetry perhaps?  All other axes are proximity ordered from the current 
node, which this couldn't be ... I suppose document order would be the only 
sensible order of an "all siblings" axis.

Of course the set is "( preceding-siblings::() | following-siblings::node() 
)" which is all siblings in document order ... but that cannot be used as a 
step in a multiple step location path.

This is just "../node()" which is also in document order.

count( ../foo[@role='bar'] ) = 1

I hope this helps.
