What the article says around this equation

Two worldlines held at accelerations a1a_1 and a2a_2 therefore differ only by which Planck-shaped curve their normalized spectrum traces, and identical accelerations trivially return DdetD_{\rm det}=0 — the reparametrization check every metric has to pass, satisfied here for the most literal reason available: identical trajectories are, in fact, identical.
