The claim and the caveat
Alpha begins there. It is not established there.
Live expectancy above the benchmark is a necessary condition for alpha and nowhere near a sufficient one, and the page's two sentences carry that entire distinction. Read alone, the first sentence licenses a trader to conclude they have found something on a single favourable reading. The second sentence exists to prevent exactly that, and the mechanism it specifies is confirmation by three independent metrics before the reading is treated as a finding. Two sentences carrying that much weight is a risk in itself, which is why the confirmation requirement is implemented as a check in the workflow rather than left as a caution in the copy.
