[graphviz-interest] dot output depends on the order of nodes in the source

Hello, all

Is  it correct that the result of dot depends on the
order in which nodes are introduced?

The following program:

digraph G {
   graph [dpi=96]

   rankdir = LR

   Export
   Condition2

   Export->GetBaseDoc

   Condition2->Export

   Condition2->CheckA
   Condition1->CheckA
   Condition1->CheckB
   Condition2->CheckB

   {
      rank=same
      Export
      Condition2
      Condition1
   }
}

produces this output:

        https://urldefense.proofpoint.com/v2/url?u=https-3A__r31.imgup.net_call-2D21f3d.png&d=DwICAg&c=LFYZ-o9_HUMeMTSQicvjIg&r=xTP9WvTdKb0ExEpJt26Gk78mnvO7k30KWj9PaePy7aZwx4MmNzMLhJV4yUhpeMDg&m=63mucJ6kCotRlhl86QbRAMm1yg6tp-5YAs6d8-Ip6iU&s=2quBE7UvjtrtJJ3RPs0w2HA3W7kWkIFKiUKEj4XJhrI&e= 

whereas revering the nodes Export and Condition2  in
the beginning:

   Condition2
   Export

causes them to be reveresed to the output also:

        https://urldefense.proofpoint.com/v2/url?u=https-3A__j07.imgup.net_call-2D2d968.png&d=DwICAg&c=LFYZ-o9_HUMeMTSQicvjIg&r=xTP9WvTdKb0ExEpJt26Gk78mnvO7k30KWj9PaePy7aZwx4MmNzMLhJV4yUhpeMDg&m=63mucJ6kCotRlhl86QbRAMm1yg6tp-5YAs6d8-Ip6iU&s=TlGIY3CPf0l3pBoRcB8yTbG6mnC03qA5OhWZX3SWLoo&e= 

This  latter  arrangement  should seem more optimal,
because the edge Condition2->Export is straight  and
much  shorter.   Why does not dot find this solution
in both cases?
