Sample Item-Set relevance

I am going through the Sample Level II Item-Set Questions but I am wondering whether they are relevant for this year’s exam. If I take for example the mini case on “Bobby Lee” there is a question about SFAS 158 in Employee Compensation. I reviewed the curriculum and can’t find any mention of it. The solution gives a reference to the 2009 curriculum. Does that mean that the sample set posted by CFAI is outdated and can’t be used to prepare for the exam? Thanks for your point of view
