An Info manual has a tree structure, so sequential order is not well
defined.  If you read the description in Help-^L, you will see that it
describes depth-first-search:

     In this sequence, a node's subnodes appear following their parent.
  If a node has a menu, <SPC> takes you into the subnodes listed in the
  menu, one by one.  Once you reach the end of a node, and have seen all
  of its subnodes, <SPC> takes you to the next node or to the parent's
  next node.
