Islam critiqued finds compromising clue; 2:187 elaborating on previous revelation?

In answer to the video "Allah's Confusing Ayah"

This verse touches upon the issue of piecemeal revelation. One of the aspects of that process was to guide the nascent Islamic movement in all its stages to suit its requirements on different occasions. It did so for example by elaborating on certain previous concise statements, either by a longer revelation in a different place or by addition of relevant information within the same previously revealed verse. We have classical examples reported in the hadith books, like 2:187 and 4:95 where the scribe present, who was being dictated the concise then more elaborate revelation, describes how the event occured supernaturally. It is a Quranic principle that one should not ask about things that if answered would render a simple directive complicated. But one may ask while revelation is descending and will be answered 5:101 as documented regarding ibn Um Maktum's concern upon hearing verse 4:95. The difference between the 2 attitudes is that of sincerity. The first one hears a directive, reflects on it and comes back after a while with conjecture, as if he is trying to avoid it. On the other hand the one expressing a concern directly when hearing a command does so out of genuine concern for a condition preventing him from immediately implementing the directive. 

The gradual revelation, progressive elaboration also gives the audience the feeling that it is being closely followed, listened to, attended to and corrected by its Sustainer, answering relevant questions of law or theology, questions by the believers or disbelievers alike, providing strong argument in favor of the truths it propounds or to counter false notions

25:32"And they do not bring to you an example except that We brought to you the truth and best of explanation".

Again this is not a strange phenomenon in the prophetic history, especially when it comes to the issue of further elaboration/explanation of a previous concise statement or ruling. See Jn3 for example. For a very detailed explanation of what piecemeal revelation consists of, this youtuber and others can go back to a previous video.
