In this case, Mr. Webster is slightly incorrect; this is technically the use at the beginning of a clause of the phrase which ended the preceeding clause (also known as epanastrophe). e.g. 'Has he a gust for blood? Blood shall fill his cup.'

A*nas"tro*phe (#), n. [Gr. , fr. to turn up or back; + to turn.] Rhet. & Gram.

An inversion of the natural order of words; as, echoed the hills, for, the hills echoed.
