Yes, that's the butterfly effect as vividly demonstrated by Ray Bradbury in SOund of Thunder. Or Isaac Asimov's classic novel THe End of Eternity where professional time travelers deivse absolutely trivial time changing events, like someone missing a phone call, that produce desirable huge impacts on the timeline, possibly many years later.

They're interesting stories, but I would like to point out that writing a story where something happens, doesn't really "demonstrate" anything in real life. Especially when it comes to time travel which may end up not even being possible.

I think it was because McCoy actually arrived later in the past time than Kirk and Spock, even though he jumped through first. But I guess he should have jumped back first and arrived back later than Kirk and Spock. Somewhat like
All Our Yesterdays (1969)
they retun the same way they left.
I will say in all these years I've watched over and over since I watched the original run of TOS as a teen I have never thought about it.
