Do you mean in the css3-page editor’s draft? The algorithm is the same 
is in this month’s working draft:

http://dev.w3.org/csswg/css3-page/#variable-sizing
http://www.w3.org/TR/2013/WD-css3-page-20130314/#variable-sizing

That is not the case. If all three boxes (eg. @top-left, @top-center and 
@top-right) have 'width: auto', they never overlap. (There might be 
overflow if there is too wide unbreakable content, aka. 'min-content' or 
minimum preferred width.)
