I see that is possible, reasonable, and a valid explanation. It is undeniable, however, that Musk knew he would have effect on Twitter's share price because he delayed 11 days in revealing his stake, saving him ~$140M on Twitter shares while everyone was in the dark. Now, maybe the market subsequently declined everywhere, but it is reasonable to assume that Musk's public statements after Twitter accepted his offer were intended to affect the share price to increase above his offer, sweetening the deal for him. It is also possible that, even though or if the market declined everywhere, that Musk did have an effect opposite to his intention: it would be incompetent to publicly announce intentions to fix something that was already profitable, which if unpopular enough, may have affected share prices negatively.
