I think he means the fee will be lower when compared to centralized exchanges, which charge you ridiculous withdrawal fees way above the amount necessary to cover the transaction fees.

Having said that, I have used peer to peer exchanges for so long now that there are a small handful of people in my local area I have traded with so many times that I now trade with them directly without using the peer to peer platform we used previously. This exposes both of us to a higher risk since we are now not using the escrow provided by said platforms, but since we have built up mutual trust over the years we can now trade without paying platform fees or additional transfer fees to and from the escrow, as well as giving each other better rates.
