Benefits and use cases for strong mobility in presence of closure serialization

I read a paper about strong mobility in Haskell http://www.dcs.gla.ac.uk/~trinder/papers/strongm.pdf and I wondering what benefits it gives in presence of closure serialization? I guess for some languages strong mobility could be only way to transfer execution state of program, e.g.

[Mobile Pascal;)]
program Test;
var
  a: Integer;
begin
  readln(a);             // acquiring on current host
  moveTo("anotherHost"); // transfering state and terminating
  writeln(a);            // printing on another host
end.

but in Haskell same program can be written just using rfork :: Host -> IO () -> IO ():

main = do
  a <- readLn
  rfork AnotherHost $ do
    print a

The difference comparing to moveTo :: Host -> IO () version is purely syntactic:

main = do
  a <- readLn
  moveTo AnotherHost
  print a
