No, they're not telling anything different. They are simply forbidding further examination of the manuscripts. The first examination was in the 1970's. They all descovered that this version of the Qur'an is not the same as the "original". The Muslims also say that it's not the same but they say it is like that because it's just a bad copy.
Now, the Sana'a manuscripts are interesting because they have two layers of script. This original script was washed off from the parchment so that it might be used again. It's nothing strange, it was a common practice back then.
But without applying special technical means the older script is not readable. All we know that it's also the Qur'an, and it's a version even older than the one dated in 649-690.
We can see the older script using ultraviolet light underneath the newer text. It couldn't have been done at the time of the first examinations. Now we can do it. But the Yemen authorities don't allow it.
Maybe they already did it and they didn't like what they read?

But hey, while the Yemeni authorities are blocking this project, maybe these people should turn their attention to Jammu & Kashmir where it is said that Jesus Christ is buried.
