Is BLOB stored in InnoDB buffer pool?

According to the article below, that compares Falcon Engine with InnoDB, InnoDB stores BLOB data in the buffer pool.
http://dev.mysql.com/tech-resources/articles/falcon-in-depth.html

In the official documentation, it is mentioned as below (http://mysql.openmirrors.org/doc/refman/5.1/en/innodb-restrictions.html):

InnoDB stores the first 768 bytes of a VARCHAR, BLOB, or TEXT column in the row, and the rest into separate pages.

The documentation doesnt state if all the pages corresponding to a BLOB are loaded when a request for a record, that has a column of BLOB datatype, is made..
