I'll have to look at this again, I'm still not convinced. Thanks anyway.

I am also not convinced. I read through the whole article and what was mentioned as "double-spend" is RBF with new outputs that the sender controls which DOES NOT work if the tx was already confirmed:
In case of manual RBF we can specify totally different destination addresses, which can be considered a doublespend.
A miner will not split the chain just to include a tx with a higher fee.

Why don't you try yourself? On your own addresses. Nothing to lose, you are just sending to yourself. Now the onchain fees are low, good for experimenting and learning this stuff.
