Play Black's moves of the line from memory — 1. e4 e5 2. Nc3 Nc6 3. Bc4 Nf6 — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 2 named lines that continue it, such as Bishop's Opening: Vienna Hybrid, Hromádka Variation, Vienna Game: Stanley Variation, Bronstein Gambit.
