Considering the following hierarchy of node types: nt:parentType,

nt:parentType, than I am wondering if a query in the form:
//element(*, nt:parentType) is gonna return both types of children (or
is it strict, meaning that the query will look only for nt:parentType
nodes and no children of nt:parentType; Than to retrieve both children
types nodes you should use //element(*, nt:childType1) or //element(*,
nt:childType2)).
this is described in section 6.6.3.2 of the JCR spec:
A type constraint specifies the common primary node type of the returned
nodes, plus, possibly, additional mixin types that they also must have.
Type constraints are inheritance-sensitive in that specifying a
constraint of node type X will include all nodes explicitly declared to
be type X, as well as all nodes of subtypes of X.
