again, only if they had separate maps and you're using P6 or lower.  so on V4, where the arms and legs and hands have separate maps, yes.  on V3 where the whole body had one map, if lots of different material zones for arms and legs, no.

for P7 and up, it wouldn't matter.  it only works with the pieces of the texture it needs at the resolution it needs, or something like that.  that's why they got rid of the max texture size feature.
