It's not the union: it's the brackets

(preceding-sibling::*[1]) is the nearest sibling

(preceding-sibling::*)[1] is teh first sibling.

as the parenthesised expression is evaluated as an Xpath value, hence a
node set , so [1] then sorts that node set and takes the first, whereas 
teh first form is a step expression in which the current node list is in
reverse order.
