The next act in the drama occurred around 200 AD when Origen produced his Hexapla or sixfold version of the Old Testament. This version contained the above 3 Greek versions in parallel, plus the MT in Hebrew, the MT in Greek, and then the LXX as revised by Origen. Note that, except for the LXX, all 5 other versions in Origen's Hexapla were simply variations on the Masoretic text. Furthermore, as Sir Frederick noted on p. 58, '...Origen's efforts were not directed towards the recovery of the original form of the Septuagint LXX, but at bringing it into harmony with the Masoretic Hebrew Text then current, and to do this he introduced alterations into it with utmost freedom.' This indeed is a serious matter, particularly as all the other versions were simply variations on the MT. Fortunately, in the year 617 AD, Bishop Paulus of Tella in Mesopotamia made a Syriac translation that detailed all Origen's alterations. As a consequence, the form of the original LXX has been preserved for us, and is today still in existence.

Is the above considered to be true?

It is from here...http://www.ldolphin.org/barrychron.html

Did Origen change the LXX only to have these recorded chages alter reversed?

It is a little ambiguous in the link
