The document is explicit that the maximum entries per NOC was 2 which was why I was confused when the commentators this morning said that some nations could qualify 3.
I think the point @Epic Failurewas raising was whether the same athlete could secure 2 quotas for their nation - qualifying through the OQS with a named quota and through the World Championship route with a second quota for their NOC. If I remember rightly back to the World Champs in Glasgow, there was a lot of discussion about whether riders could qualify 2 spots for their nation. Hannah Roberts for example had "won" a quota at both the 2022 World Champs and 2023 World Champs and that seemed to be acceptable under the terms of the qualifying document as it stood at the time.
However, I see that the qualification document has been updated in February of this year which means that the 2023 world champs quotas will be reallocated to NOCs that have not qualified through the OQS although strangely, they haven't changed the terms for the 2022 World Champ quotas.
Anyhow to answer the question @Epic Failurewas raising, no Declan Reilly can't double qualify GB unfortunately. And more than that, if Hessey or Jones gets into the top 6 and he doesn't, then the world champion would miss out on Paris all together.
