Probably because the first expression selects the singleton text child of a
single MembershipFee element, whereas the second expression selects the
children of every MembershipFee element that is the first child of its
parent. Try "instance of text()*" to verify this.

//X[1] is a common error when (//X)[1] is intended. Or it may be better to
write /descendant::X[1] for clarity.
