Explained in the _TeXbook_, page 106:

     If a line break occurs at the \penalty50, the \hskip2em will 
disappear and the empty
     \hbox will occur at the beginning of a line, followed by \hfil 
glue. This yields two lines
     whose badness is zero; the fi
rst of these lines is assessed a 
penalty of 50. But if no line
     break occurs at the \penalty50, there will be glue of 2 em plus 2 

fil between the review
     and the name; this yields one line of badness zero. TeX will try 
both alternatives,
     to see which leads to the fewest total demerits. The one-line 
solution will usually be
     preferred if it is feasible.
