As a graduate of the UC-Berkeley (Boalt) School of Law, and an admissions consultant for Write Track Admissions, I can personally testify that although Boalt provides you with (a maximum) of four pages, it is preferable to have a statement that is actually shorter, more focused, and thus less susceptible to being skimmed by the admissions committee. Therefore, your statement is fine at 2 pages if the content is polished and compelling. Also, however, consider if your application would benefit from an addendum.
Best of luck, and please contact me if you have additional questions.
