They don't care. The diff between the two, I'm pretty sure, is that Biochem 360 is a one-semester sequence and the Biochem I 462 is the first course of a two-semester sequence, in which case you would then have to take the second course in the sequence. There are pro's and con's of the one- vs. two-semester sequence, so decide for yourself if you would rather cram biochem in one semester (quicker, less in-depth) or take the full-year route (will probably be better preparation for medical school but will be more in-depth, and you might get annoyed with biochem by the end of the year).
If your school is like mine, the two-semester sequence course is mostly full of biochem majors while the one-semester sequence is mostly full of premeds.
