The training one is not really the important one, but regardless the function is there. This just puts rules to it.
The digital transference is very limited the person only gets the mental. Eg, a person can download flying a shuttle, they know the theoretical and procedures, but they don't have the actual hands on that they need to do complex stuff.
Its not going to let you download data a make an instant superspy. And for alien species outside of Yamatai its a non-issue because the Halo hasn't been programmed for their brains.

FYI, I have updated the HALO page to reflect the species that it is compatible with.
