Is tunnelling from nothing a transition?

Sorry for my abysmal level of ignorance, but I'm not understanding why quantum tunneling from nothing is considered a possible starting point for a multiverse, when the permanence of our pocket universe within the multiverse is also considered to be threatened by a phase transition if its vacuum has any pairing of masses for the Higgs boson and top quark lower than those in a certain sequence of pairs. Would a pocket universe whose Higgs and top-quark pair were at any mass be threatened with a (possibly lower) risk of annihilation by quantum tunneling from nothing, or might it just blink off for an interval (perhaps imperceptibly short) if their masses were consequently left inadequate for stability?
