Reporting just the percentages makes sense. Reporting rounded versions of those percentages not only makes sense, but is the universal idiom for reporting percentages. But reporting synthesized vote counts from the percentages --- even from non-rounded percentages --- is not normal.
People on this thread are hung up on the reported percentages, but those don't matter in this analysis at all. They're not the problem. The problem is the counts themselves. Discard the reported percentages entirely; exact same critique, one statistics students would spot instantly.
Maybe I don't understand what you have identified as the problem. My understanding of the article is that the raw tallies should not correspond to "precise" rounded percentages. The article in an addendum points out one way that could legitimately occur (some underling has the totals and rounded percentages but needs the raw tallies and naively multiplies to get them).
I'm summarizing that PPS in my comment. The exculpatory scenario is: (1) start with real numbers, (2) compute percentages, (3) round percentages, (4) discard original numbers, (5) compute new numbers from the round percentages.
Steps (4) and (5) don't have any valid explanation, and few (though maybe some) plausible human error explanations.
As long as we're on the same page that nobody ever had any business reporting the numbers in step (5) --- they're completely fictitious! --- I don't have much to argue about here. The politics aren't interesting to me.

It does... Person A didn't send the original numbers to Person B. And then Person B wanted to publish a document that showed the original numbers anyway (maybe they were asked to by a media person or something). And they did the glaringly obvious calculation of g% x total_votes and called it a day instead of being delayed for hours or days waiting for a request for the original numbers. This is really a very common scenario that happens everywhere in multiple fields.
