are both for P# 274, a commemorative note (1st page includes the basic commemorative note as well as additional years as listed in Standard Catalog of World Paper Money, Modern Issues, 20th ed., 2014, p. 466).
This is a great question, it is also a difficult consideration on the coin side, where people and some refs wish to deny a coin status as a FAO coin because a design is used on more than one year.
Feedback will be interesting.
My gut instinct is to consider the issue to be commemorative, since there is no text changes. It is odd and confusing to have two different listings with the same number. It is also my gut instinct to have just the one listing with a comment to the effect that the first note is a commemorative...although all technically are since there is no text changes.
Several questions must be hashed out. How do we address the catalog number if we decide to have more than one page? Since the catalog number is the same for the commemorative and the subsequent years of issue, is a comment to the effect of just the first year is a commemorative enough? Now that we have decided how to handle this, will it be applied the same way to all other notes in the commemorative series? How do they do it on the coin side? The first year of the US Washington quarter is not in a listing of its own...it is denied its commemorative status. Should this apply with Haiti? Haiti is not the US. How are similar listings of Haiti arranged? Does Haiti have a ref? What is the ref's thoughts?
Then a decision can be made. And hopefully it will be to the ref, the team, and the collector's of Haiti banknotes satisfaction. But even if it isn't hopefully it can be understood why.

I assume Haiti needed more banknotes and it was easier to just keep the commemorative design and wording than pay for designing a new note. For some reason the date was not retained but I would be in favor of all the dates with the same P# being on one page. And for coins I have no trouble accepting the idea of multi-year commemorations for the FAO, for example.
The problem right now is that the initial Haiti note is listed on the multi-year page as well as having a separate entry.
