74ALVC164245ZRDR Moisture Level

TI p/n 74ALVC164245ZRDR, is listed on TI's datasheet as being MSL1.  Being a silicon BGA, I don't see how this is possible. 

I think it should be MSL 3.  After digging around today, we found the following on the attached .pdf:


"ï Moisture absorption also affects the ball off issue. The package was qualified at Moisture Level 2, and has been released at Moisture Level 2A.  The first and second reflow must be completed within 4 weeks."


This notice was published in the last few days.  2A is better than 1, but still not my anticipated 3.  Can someone confirm the rating?
