It's not the implementation, it's part of documented behavior of DEL:

  Scroll one screenful back in Info, considering all nodes as one
  sequence                           ----------------------------
  --------

IOW, DEL (and SPC) move between nodes of the node tree in the
depth-first-search order.  And l moves back in the same order.

Feel free to suggest this change on the Texinfo mailing list.
