As others have observed, this is the defined behaviour for nodesets.
For example, given the nodesets NS1: {<a>-1</a>, <b>0</b>, <c>1</c>} and NS2: {<X>0</X>}
this means that all of the following relationships hold:
NS1 = NS2 (the string value of the node <X>0</X> in the second set is equal to the string value of the node <b>0</b>)
NS1 != NS2 (the string value of the node <X>0</X> in the second set is not equal to the string value of the node <a>-1</a>)
NS1 < NS2 (the string value of the node <X>0</X> in the second set is > the string value of the node <a>-1</a>)
NS1 > NS2 (the string value of the node <X>0</X> in the second set is < the string value of the node <c>1</c>)
NS1 >= NS2 (the string value of the node <X>0</X> in the second set is >= the string value of the node <b>0</b>)
NS1 <= NS2 (the string value of the node <X>0</X> in the second set is >= the string value of the node <b>1</b>)
