This is intended behavior.

After an afternoon of research I have discovered that:
The resolution to Bug #35785 caused this problem.
CVS Revision 1.192 (by Helly) was the commit.
I have to agree with php at bouchery dot com that this is unfortunate
behavior. Who would expect that their structure would change just
because they read it?

If there is no nodes, I browse like an array, no data is display, but a
node was created. If I do it twice, it display something !
Browsing tree MUST NOT create node.
Look at this :
<?php
$xml = simplexml_load_string('<root></root>');
foreach( $xml->a as $a ) echo "a = $a\n";
foreach( $xml->a as $a ) echo "a = $a\n";
?>
A the second time, it display : "a ="
Sorry to insist, but it is not "normal" (and I can't see that in the
documentation !!).

I didn't see that in the documentation.
Even if it's written, it's a strange behaviour and shoud be a change
request.
Reading data should not modify it.
