Converted Indent-Bug.odt -> .docx

I cannot reproduce this behavior using LibreOffice Version 4.0.1.0+ on Ubuntu 12.04. I followed the format of a bulleted list as you created it, using shift + enter or the space bar to indent. After I close and reopen the .doc and .docx, the formatting is still the same between either of those and the original .odt document.

I will close this as WORKSFORME, but if it's still a bug for you, or if you have other info or scenarios about this occurence, you can REOPEN.

Reproduced using Version 4.0.0.3 (Build ID: 7545bee9c2a0782548772a21bc84a9dcc583b89)
Ubuntu 12.10

It is Backspace not space bar. I indent with Backspace as follow: 
1. Hit Enter (Automatically new Bullet is inserted)
2. Hit Backspace (<-) Bullet disappears

My mistake, thanks for commenting again. I see that when you use the backspace to erase the bullet, the .docx and .doc files don't retain the formatting. This was confirmed using LibreOffice 4.0.1.0+ on Ubuntu 12.04. Thank you for reporting this!

I've done some more research, below are differences in flat odt files.

     <text:p text:style-name="P3">Indent <text:span text:style-name="T1">(Backspace)</text:span></text:p>
    </text:list-item>
    <text:list-item>
     <text:p text:style-name="P2">Test1</text:p>
    </text:list-item>
   </text:list>
Indent-Bug2.fodt (this was done odt->docx->fodt):
<text:list xml:id="list4803795411" text:style-name="WWNum1">
    <text:list-item>
     <text:p text:style-name="P2">Test1</text:p>
     <text:list>
      <text:list-item>
       <text:p text:style-name="P2">Test2<text:line-break/>Indent (Shift+Enter)<text:line-break/>Indent (Shift+Enter)</text:p>
      </text:list-item>
      <text:list-item>
       <text:p text:style-name="P2">Test2</text:p>
      </text:list-item>
     </text:list>
    </text:list-item>
   </text:list>
   <text:p text:style-name="Standard">Indent (Backspace)</text:p>
   <text:p text:style-name="Standard">Indent (Backspace)</text:p>
   <text:list xml:id="list2091705632" text:continue-numbering="true" text:style-name="WWNum1">
    <text:list-item>
     <text:p text:style-name="P2">Test1<text:line-break/>Indent (Shift+Enter)</text:p>
    </text:list-item>
   </text:list>
   <text:p text:style-name="Standard">Indent (Backspace)</text:p>
   <text:list xml:id="list1087656376" text:continue-numbering="true" text:style-name="WWNum1">
    <text:list-item>
     <text:p text:style-name="P2">Test1</text:p>
    </text:list-item>
   </text:list>

Differences are:
1. When Indent with Shift+Enter there is 1 paragraph <text:p>...</text:p> with line breaks
   When Indent with Backspace there are 3 paragraphs no line breaks
2. In Indent-Bug2.fodt paragraphs with "Indent (Backspace)" are outside list <text:list>...<text:list>

docx file to test what Word creates

Word does the same when hitting backspace the first time, at the start of an empty line with bullet. But different the next time you hit backspace there.

I attach a docx with the test, and in a moment the same, saved as ODT in WOrd2010
