It's not just that. I can try to provide some insight about how he and his manager would be thinking. If he were to accept loan offers, like from Hull, or another Turkish team besides the three bigs (Galatasaray, Beşiktaş, Fenerbahçe), then here in Turkey the audience is thinking that he is mostly done for.
It is much more easier for him to make his marketing claiming "Everton was just a bad spell, things did not work out", BUT, if he will go on loan right now and fail there also, he will not be securing a contract even in Turkey.
Also, his former team, Beşiktaş, will be holding presidential elections in May and bringing back Tosun would definitely attract some votes from the congress. In Turkey we do not have ownership system of the clubs, you just become a member and vote for running president candidates for 4-5 year terms.
So, I think, it is mainly to mask how bad he is right now.
If you call him fat, you should see the so-called legendary midfielder we gave to Watford; Ozan Tufan. Some fans hated him here, some were thinking he would be playing so well not in Fenerbahçe, but in PL. He is so fat, even in PL, even with PL trainings that he cannot even play. We pray for Watford not to relegate, because his loan will turn into definite signing if they will not relegate for like 9 mil euros.
