Sounds like the quote from the article is using the term "gas fee" to refer to the overall transaction cost. At least I don't see any reason why someone would specifically car about the gas fee portion of the overall fee in the context of losing most of the money in the refund process.

Users focus a lot on the gas price since it's a consistent indicator of the cost to transact, so they've tended to use the terms "gas fee" and "transaction fee" interchangeably. Your transaction fee is used entirely to buy gas, which is spent in running your transaction.
