Indeed, you are correct (BIP125 rule 4[1]).
Thanks for the correction,

[1] For the curious, the relevant code from master's validation.cpp:
// Finally in addition to paying more fees than the conflicts the
// new transaction must pay for its own bandwidth.
CAmount nDeltaFees = nModifiedFees - nConflictingFees;
if (nDeltaFees < ::incrementalRelayFee.GetFee(nSize))
{
return state.DoS(0, false,
REJECT_INSUFFICIENTFEE, "insufficient fee", false,
strprintf("rejecting replacement %s, not enough additional fees to relay; %s < %s",
hash.ToString(),
FormatMoney(nDeltaFees),
FormatMoney(::incrementalRelayFee.GetFee(nSize))));
}
