Camcording/recording/filming techniques?

I will be getting a new camcorder at the end of the month or next month and I will start vlogging or something like that.
So, I have seen some videos on YouTube of people when they vlog and I have noticed that when they vlog at one point they stop or pause the camcorder and then suddenly there’s another scene.

For an example like this video http://www.youtube.com/watch?v=0F2nqTBrxqA
It starts at a scene then it skips scene thus it jumps forward, if you know what I mean?

And I was wondering how you do that? Is it by editing the video or do they actually pause the recording or something? Becuase I will be getting a Canon Vixia HF S10 camcorder and I want to vlog but I don’t know if it’s possible to pause the recording then jump to another beginning like that or is it all in the editing?

So let me know how you do it and how you guys record, your techniques and stuff like that.
