Correct.  He doesn't have enough rets in there, but otherwise it would be
fine.  This for example will work fine:

  call label1
  ...
label1:
  call label2
  ret
label2:
  call label3
  ret
label3:
  ret

you can, however, put a jump in there if you so please, but remeber you're
still gonna need the rets in there.  So this will also work:

  call label1
label1:
  cp  5
  jp   nc,label2
  ...
  ret
label2:
 ...
 ret
