I would guess that the difference he means is one between a recipient
and a beneficiary. I can certainly differentiate the two, and so does
English for the most part for that matter:

I sent the letter to him != I sent the letter for him

Unlike most Romance languages and many other languages, English doesn't
generally allow a beneficiary to be marked by "to" on its own, although
of course you can form constructions involving "to" to indicate a
beneficiary, eg "to his benefit".
