"If there are several predicates in the StepPatten, then position() and
last()
in predicates after the first apply to the nodes that survived the previous
predicates"
yes that means if you have
b[something][2]
then you get the second b for which something is true.
as opposed to
b[2][something]
in which case you get the 2nd b (if something is true) and nothing
otherwise.
But your something was true() and
b[true()][2]
is the same as
b[2]
or b[1+1] or any number of equivalent expressions.
