From what I observe he follows this "second cycle" pattern to get himself motivated. He changes his swing, changes coaches, fights through injury, comes back from surgery, and now back from a personal crisis of his own making. He seems to need this to get himself motivated to put in the practice and maintain the intensity to be the absolute top.
Yes, I'm reminded of those that break things, just so they can fix them. I suppose it's about the process in general. I think the idea of generating power need not be questioned, I agree with it. There is a drive that precedes the generation of power though. I think, in terms of the theory, Crafters aren't "comfortable" with others "having" power over them; the only limits they want are those they impose on themselves.
There is a struggle between realizing a potential and accepting limits. I've obtained a copy of the book Outlier by Malcolm Gladwell and I will get around to reading it eventually
Here's a quote from Bruce Lee (wikiquote)
* As an instructor, you must be able to distinguish between poor performance caused by lack of ability or aptitude on the part of the student and poor performance caused by lack of effort. You should treat the first with patience and the latter with firmness. You must never apply sarcasm and ridicule.

Here's a favorite quote from Hubby that I like to:
"If you ever find yourself looking at an on-coming nuclear missile and holding a rock, before accepting your fate, you might as well throw the rock at it"
