How have courts interpreted the meaning of the Three Strikes law in the context of reduced sentences for "heroic acts"?

The purpose of the Three Strikes law is "to ensure longer prison sentences and greater punishment for those who commit a felony and have been previously convicted of serious and/or violent felony offenses." ( 667, subd. (b) [legislative intent applicable to subds. (b)-(i) inclusive].) Allowing Three Strikes prisoners to receive at most a one-year sentence reduction for performing a heroic act ( 2935) does not undermine this purpose: these recidivist prisoners are still serving longer sentences than first-time offenders. Moreover, "our decisions make clear that this purpose is not a mantra that the prosecution can invoke in any Three Strikes case to compel the court to construe the statute so as to impose the longest possible sentence." (People v. Garcia (1999) 20 Cal.4th 490, 501, 85 Cal.Rptr.2d 280, 976 P.2d 831.)
