Is it really a good thing if a judge “never complains, never explains”?

This news article about a controversial judge was interesting on many levels, but my favorite bit was this:

“Sharon is a hard worker,” said Dan Hagood, a defense lawyer and longtime friend from Dallas who served as her campaign treasurer when she ran for election to the court in 1994. “She never complains, never explains.”

“Never complain, never explain” is a reasonable motto for some, I’m sure. But for a judge??? I’d think explaining is a key part of the job.
