They did that to link it in with Legend, which is still kinda hamfisted but really who cares because she talks for 20 seconds and then you're in a tomb. Actually a little longer because the new first level lets you play the CG sequence that started TR1.
With regard to TR Anniversary specifically, the story/character changes were definitely not a big deal. But I think RagnarokX used this as a representative example of what he saw as an unfortunate change in the Lara Concept, a conceptual shift that persisted in subsequent CD games and finally ended up mattering in a bigger way by the time of TR2013 and RotTR (a point of view described further by Lime and Messofanego). I was hopeful when I started up Blood Ties/Croft Manor in RotTR recently, for example (right after my first playthough of the amazing Gone Home, it should be said) and I found the cringe factor to be pretty high, so I'd tend to agree with their criticisms of the character/conceptual shift; but I do know a lot of folks seem to like the new/CD Lara. And in any case as you pointed out, none of this really matters much with regard to Anniversary specifically (also didn't know that CD made this particular change to ensure consistency with Legend).
