Recently a tachyon DBI action is proposed for describing the non-coincident Dp-brane-anti-Dp-brane system. For brane separation larger than √{2π2α′}, the tachyon potential has both false and true vacuums. We shall show that due to the non-standard form of the kinetic term in the effective action, the thin wall approximation for calculating the bubble nucleation rate gives a result which is independent of the brane separation.
