lds apostle is a special witness of the *name* of jesus christ?

An Apostle is a special witness of the name of Jesus Christ in all the world (see D&C 107:23). The Apostles administer the affairs of the Church throughout the world.

i wonder if this is a typo?

update: no, its not a typo, i also read it in the reed smoot hearing transcript
it is also worded that way in the doctrine and covenants:

The twelve traveling councilors are called to be the Twelve Apostles, or special witnesses of the name of Christ in all the world—thus differing from other officers in the church in the duties of their calling.

the weird thing is that the seventy are defined as what you would assume the apostles to be defined as:

Seventies are special witnesses of Jesus Christ to the world

but another weird thing is that on the gospel principles page on lds.org it states the opposite:

A prophet, acting under the direction of the Lord, leads the Church. This prophet is also the President of the Church. He holds all the authority necessary to direct the Lord's work on earth (see D&C 107:65, 91). Two counselors assist the President. Twelve Apostles, who are special witnesses of Jesus Christ, teach the gospel in all parts of the world. Other general officers of the Church with special assignments include the Presiding Bishopric and the Quorums of the Seventy.

reference: apostles no longer special witnesses of jesus christ. who knew?
