The anniversary buff was a 100% increase in legendary drop rate. The rift buff is a 100% increase in legendary drop rate (formerly 25%, as shown in OP's quote). I'd imagine this means that, when in a rift, you have a 200% increase in legendary drop rate, multiplied by the torment bonus and the magic find bonus.
I could be wrong on the 200% part, but I'm fairly confident on the other part.

I too am curious what the numbers would be. It wouldn't affect my play, but I enjoy seeing the numbers
