The form
2 bars move to a second chord partway through. The transcription writes hands for the first chord only, so the second is printed and not drawn rather than invented.
One bar carries two chords. The transcription writes both chords' notes together without saying which note belongs to which, so that bar is printed and not drawn — a keyboard guessed from an ambiguous line would show a chord nobody plays.
The hands
Left hand then right, as the source writes them. A pianist's voicing routinely carries a colour the chord symbol does not spell — a flat ninth over a dominant, a ninth on top of a seventh chord — so the notes printed under each keyboard are what is actually played, rather than what the symbol alone would predict.
