With review of my stance I have come to conclusion that Merging and Splitting are severely different. This is all because abrupt ending of a timeline is not Low2C destruction but 3A. Creation is still solid low2C or 2C depending on how many 4D constructs are involved.
I will probably get lot of hate for this opinion, but once you go to far its not possible to convince yourself to stop let alone backtrack.
Splitting.

As seen and I already explained splitting process is essentially stopping the timeline at a point which is 3A, and from that point on 2 new timelines are formed. And since both feats are done in tandem... its 2C as whole.
Merging.

This is same principle as above, but difference is in counting, as crazy as that sounds.
So abruptly ending 2 timelines on convergence points is 3A or 2×3A to be exact,
But from that point formation of singular timeline is Low2C.
So Merging as a whole is Low2C.
Of course if the original timeline or timelines before convergence or divergence are
destroyed completely then you get Solid 2C in both cases. Since complete destruction of timeline is Low2C and doing it to multiple timelines is 2C. So both destruction and creation end up covering each other's asses in the process.
Hope I don't get burned on stake for this.

Why wouldn't the perceived destruction in erasing a few seconds of time not technically be Low 2-C? (I mean, I argue it isn't, but I think from your logic it follows).
Currently this is not accepted here on this wiki. Why is this so I am open to discussion. But as of know I am neutral on this.
I think giving 2-C based on that perceived creation/destruction is similar to giving Low 2-C based on perceived destruction in erasing a small segment of time.
After I have reclarified, I think this a wrong comparison in my opinion. And this segment arguement doesn't affect splitting and merging at all since it never even comes into play in anyway.
