A Question on Style bias/style fit/SRI (regarding to Equity Portfolio Management)

Hey guys, a question on style bias/style fit please:

In “Socially Responsible Investing” section, it says " Return-based style analysis can detect the presence of syle bias and monitor the success of its remedy."

My question is:

Is ths “style bias” here same as the “style fit” mentioned in sector “return-based style analysis”?

Quoted as below style fit from earlier section “return-based style analysis”:

"From the regression, we are also provided with the coefficient of determination (R^2). This provides the amount of the investor’s return explained by the regressions style indices. It measures the _ style fit _. _ One minus this amount _ indicates the amount unexplained by style and due to the manager’s _ security selection _.
