Beatles CD Singles Collection

I was wondering if Pat or somebody could help me with this. In 1992, I purchased this box set, and it is an EMI import from Great Britain. I also recently purchased one that is the domestic release because I thought it might have different singles in it like the U.S. and U.K. did with the Elvis #1 single box sets. The domestic Beatles set has a bar code sticker that matches Pat's ID in the database (Parlophone 15901). However, I peeled back that sticker from the top of the shrink-wrap, and beneath it is a sticker that has the exact same manufacturing ID and bar code as my 1992 UK import box. My questions are: Is this a sure-fire guarantee that both boxes have the same 22 discs in the same mono and stereo versions? Putting it another way, does this guarantee that my 1992 UK box set is the same as the one Pat identifies as Parlophone 15901? If so, I am returning my new domestic box as I have yet to open it. Any help provided is greatly appreciated. Thanks for everybody's time as I realize this a long post.
