Actually, while the dimension points to the upper right hole in the figure you both reference, the axis of the pattern is the meaning of datum B, not the axis of that one hole. The 'means this' section of the figure makes that pretty clear I think.
Having said that, I agree with Kenat about being skeptical of exactly how this has been called out. I'd prefer to see something that matched the spec example more closely (just because it's easier to point at and say 'this is what I/it means'), but I don't think the print you give is wrong relative to the standard.
All this assumes that you (and your engineers) are working to the Y14.5M-1994 standard - which is just a guess on my part, since I don't see a callout on the print.
