The Uk example you’ve given is terrible. Trade execution at the quotes given (that last 30 seconds) improved. In the uk quoting is done by an RSP but It doesn’t mean the price the customer got in the end improved looking at the main board or dark pools (which you can’t see). They mention it in the conclusion of the PDF.
What it implies is price changes with payment for order flow the order won’t executed and is requoted, whereas where it’s banned there’s no incentive to cancel so you get the quote.
