As I've said elsewhere, I think that kind of forced synchronicity is asinine and stupid no matter which show does it. Believe me, I don't think Discovery is any sillier about that kind of thing than other shows and I'm not calling them out any moreso than I have other shows.
Discovery has other problems that do not involve fan-wankery-as-an-insipid-attempt-at-cultivating-faux-nostalgia-in-order-to-rope-in-TOS-fans. Those problems have a far greater deleterious impact on the show than something as silly as this. Truly, having the Enterprise conveniently show up is the least of Discovery's issues. I was merely pointing out how unrealistic it seemed to me, even given the paradigm of magical thinking already established over the course of many shows and movies.
YMMV.
