The license is indeed similar to the MIT, however the disclaimer text
the user is required to include in redistributions (the two paragraphs
in upper case) is distinctly different from that in the MIT license,
so they are not directly interchangeable.

Regardless of legal similarities, historically, the license did
originate from UC Berkeley, though where their lawyers got it from is
anyone's guess. For all I know, MIT may have got it from them and then
popularised a modified version of it :-)
