Confused about the "beneficiary" of a trust

[Benjamin Cowles]

I've read that in a trust, (ir)revocable it's usually those designated to 'benefit' by receiving the assets in the trust created by the "grantor" but that in a land trust it is the the grantor,  or the lender in a deed of trust who is the "beneficiary" rather than those that benefit by ending up with asset the trust was intended to impart the ownership of unto like in a regular trust. Seems a little inconsistent no? Is there any more sense to make of this or is this just how the terms came to be?
