Using the normal convention of upper case being  right-to-left:

Logical: "He said: I SAW THE CAT"
Visual:  "He said: TAC EHT WAS I"

Broken in logical order:

 He said: WAS I
 TAC EHT

Broken in visual order (incorrect):

 He said: TAC EHT
 WAS I

When reading a bidirectional text in Arabic or Hebrew, you never 
go up to a previous line ... lines are always in logical order.
