True enough, but there really are at least two alternatives here that could be distinguished, except that we do not have sufficient information to make this distinction. In either of these two cases, the reviewer presumably did not understand the meaning of the statement, but in the first case this was because they did not know the language sufficiently well, while in the second, they lacked the critical reasoning skills to correctly discern its meaning. In the first case, but not the second, the reviewer's performance on this particular task would vary depending on the language it is expressed in.
Of course, in neither case should the person be given the job of reviewing English-language tweets.
There are additional possibilties, such as Twitter having created an environment in which it is much safer or easier to agree with the initial ruling, or where the reviewer is required to pick from a list of justifications for reversing the initial decisions, and none of the options fit (I'm sure you have seen questionnaires like that.)
The one thing we can be sure of is that the Bishop should not have been banned.
