  Nop.  The format of if-else is:

    if ( condition ) then
      sequence-if
    else
      sequence-else

  There is no 'return' keyword there.  Remember the aim of the
instructions is to build a sequence, not to break the evaluation (then
it will be maybe more clear why no 'return' keyword is needed).
