That documentation is in error (my fault).  Current docs say

xmax

     The identity (transaction ID) of the deleting transaction, or zero
     for an undeleted tuple. It is possible for this field to 
     be nonzero in a visible tuple: that usually indicates that the
     deleting transaction hasn't committed yet, or that an 
     attempted deletion was rolled back.

No, it wasn't.
