When would I apply this technique?

You would deliver multiple strikes from different angles

What is my goal with this technique?

The altercation has escalated to strikes, multiple strikes are needed to stop the opponent and make your escape.

Common mistakes with this technique:

-people tend to drop their guard to see if their strikes were effective, when your guard is dropped you are in danger of taking a strike directly to your face. Stay in guard, hands up at all times.

-after strikes, people sometimes fail to step back, now they remain in range for your opponent to strike you.
