Razorflail Succubus and generating attacks

A tournament organizer in our local store interprets generating additional attacks from Competitive Edge in his own way. First of all he is not trying to homerule this thing, the tourney is supposed to be in WTC format.

In his opinion you should resolve the attacks rolling 2 dice separately. If both of them are failed to inflict a wound then you generate additional attacks. If only one roll fails then – no additional attacks.
Why so? Because:
As the razorflail rule states that you make 2 hit rolls for each attack, the model makes these 2 hit rolls and it counts only as one attack. And if none of these hit rolls gets to the wound allocation step, there could be no additional attacks.

Please guys, I know you can explain why it is wrong and give some quotations from the rule book. Appealing to Goonhammer articles or Nick Nanavati’s games is not the way out as “these guys always makes mistakes”.

To be honest, I can kind of see where he's coming from. The core rules don't actually allow for the possibility of more than 1 hit roll for an attack so it's never addressed anywhere that I can see. That being said, the attack sequence deals with one hit roll at a time.

Doing it the TO's way would slightly gimp the razorflails/CE combo but does nothing to address it doubling subsequent attacks and also would take forever to resolve.

His reasoning is sound except he has not read the FAQ for the Grand Tournament Pack 2020. Below is the relevant entry.

*Page 91 – Rare Rules
Add the following:
Attacks That Make Multiple Hit Rolls
Some rules, typically weapon abilities, tell you to roll more than
one hit roll for each attack made , e.g. ‘each time an attack is
made with this weapon, make 2 hit rolls instead of 1’. In these
cases, each hit roll is treated as a separate attack that is made
against the same target. As such, all normal rules that are
triggered by attacks, or that apply to attacks (such as re-rolls or
modifiers conferred by other rules) apply to each ‘hit roll’. Note
that these additional attacks do not themselves result in more hit
rolls being made.

If a rule tells you to make more than one hit roll for each attack
made, each hit roll is treated as a separate attack made against
the same target

This is why I love this forum. Thank you!
