Why is it like this
That is going down a rabbit hole. Why is the sky blue? Why is the world the way it is?
Our opinions as to how similar the situations are is irrelevant. You are looking for an internal logic that does not exist. The Immigration Rules have been added to, amended and updated by different governments over time and there is no internal logic to them (I think that was mentioned in a court judgement, but I don't recall which one).
The Immigration Rules for Tier 1 and Tier 2 provide for different requirements for ILR. In the requirements for Tier 2(G), you are allowed to include years under certain visas, in Tier 1(E), there is no such provision.
See
Immigration Rule 245DF for the requirements for ILR for Tier 1(E) applicants and Rule 245HF for the ILR requirements for Tier 2(G) applicants. In particular look at 245HF(b), which has no counterpart in 245DF.
