I went ahead and called the Plat Rewards line and talked with an agent. Basically, there is no limit to the number of points "transfered" each year. Given I currently have about half the points needed for a TP award, she said there was no issues with transferring the other 100K plus points into my account needed to order that award.

Also, she stated that if I then later in the year want yet another TP award, I can again transfer however many needed points into my account for that award.

The 50K limit is really just for purchased points, not for transferred points.
