I do not catch what the it means?

Question

Could anyone help to clarify this energizer. I cannot understand the final sentence "send additional rounds of handclaps around the circle, chasing the first" why? and what fun
Pass the beat:
Have all participants form a circle. To introduce the exercise, say: ‘I am going to face and make eye contact with the person on my left, and we will try to clap our hands (or make another noise) at the same moment [demonstrate]. Then, she or he will turn to the left and clap hands at the same time with the person next to her or him. We will “pass the beat” around the circle. Let’s try it now and remember to make eye contact and try to clap (or make the other sound) at the same time.’ The rhythm builds up and the facilitator can call out ‘faster’ or ‘slower’ to increase the speed. Once the handclaps have passed around the circle, say: ‘Now we will try to make the rhythm go faster and faster. Always be ready, because we might send additional rounds of handclaps around the circle, chasing the first.

Answer 1

It sounds like a fun exercise to build team spirit. Its like a wave at a baseball game. An action is performed by one person and the next and the next all the way around the circle. That's one wave. There are multiple waves in your exercise.

For example, person one starts the wave: they do the clap thing. Then two turns to three, then three turns to four, etc. The clap goes down the line. then one can start a new clap going...

Answer 2

Perhaps it means that instead of sending a single hand clap sound around the circle, that a different rhythm of multiple staccato hand claps would be introduced by the lead person.
