This is the expected behaviour. According to section 5.2.1 of XPath
1.0[1], "An element node may have a unique identifier (ID). This is the
value of the attribute that is declared in the DTD as type ID. No two
elements in a document may have the same unique ID. If an XML processor
reports two elements in a document as having the same unique ID (which is
possible only if the document is invalid) then the second element in
document order must be treated as not having a unique ID." The unique ID
is used in the definition of the id() function in section 4.1 of XPath
1.0.
