No, that was closer to “more wood/fewer arrows” (but that was more about aimless toys than deliberate moonshots), which was several years before Alphabet.

Alphabet was to more cleanly separate (in branding and organizationally) the core Google business from other ventures, which moved the moonshots out of Google proper. It wasn't to kill moonshots, though it may be accurate to say it was in part about being better at maturing them.
