I don't think that the article was about miscounts, otherwise it would equally be a problem for a 258 axle train that missed 2 axles. Since the article is describing a problem that occurs for multiples of 256 it is almost certainly a counter overflow issue, so a 256 axle train resets to zero and a 257 axle train would appear to the counter as 1, which is still sufficient to mark the block of track as occupied.
