Of course it makes sense. You see the lines, you see what they do and it adds confidence because they are doing it. It's the cornerstone of the 'tow'. We all do it to get better.
You just have to be careful not to get sucked in too far because the crash is going to happen not because you or your bike can't handle it. It is going to happen because you THINK one of you is in over your head and you panic and do something retarded.
I know you know that, just pointing it out.
