script – Why are signatures completely different for inputs from the identical tackle in a single Bitcoin transaction?

I’ve been learning Bitcoin transaction signatures and observed some attention-grabbing patterns when analyzing transactions involving the identical tackle in numerous contexts. Listed below are my observations.

Case 1: Similar tackle, two completely different transactions (T1 and T2)

As anticipated, for 2 separate transactions originating from the similar tackle, I noticed the next witness knowledge:

30450221008dbd2c3c33413a58d0217897daa9cfe75a7aaad3d80d915ed74dbfbc7dc70d43022034a8328a99065ff8f47acb9da4ce213ee6bf90448580cfd5129e36f39a985c3801 023b6bdc0869a329e9d0cb036257eff362aeab11512668090746bf31647a42039e

3045022100cc584f8b3c0a23d5531d1e46b15e10be7138409c46c04a16716af89ea8a653ec02202a1e364f7c2b0f4f6e995bf73b65a4ed86e5166f9c7544a397a6c38b8db4a43301 023b6bdc0869a329e9d0cb036257eff362aeab11512668090746bf31647a42039e

Right here, I assume/guess that:

1. The first hexadecimal string within the witness is the signature, and
2. The second hexadecimal string is the general public key.

As anticipated:

1. The signatures are completely different as a result of every signature is tied to the precise transaction.
2. The public key is similar because it corresponds to the tackle.

This is sensible as a result of the signature era course of incorporates the transaction knowledge (or its hash)…. however:

Case 2: A transaction (T3) with two inputs from the identical tackle

Once I analyzed a single transaction with two inputs, each originating from the similar tackle, I noticed the next witness knowledge:

30450221008dbd2c3c33413a58d0217897daa9cfe75a7aaad3d80d915ed74dbfbc7dc70d43022034a8328a99065ff8f47acb9da4ce213ee6bf90448580cfd5129e36f39a985c3801
023b6bdc0869a329e9d0cb036257eff362aeab11512668090746bf31647a42039e

3045022100cc584f8b3c0a23d5531d1e46b15e10be7138409c46c04a16716af89ea8a653ec02202a1e364f7c2b0f4f6e995bf73b65a4ed86e5166f9c7544a397a6c38b8db4a43301
023b6bdc0869a329e9d0cb036257eff362aeab11512668090746bf31647a42039e

On this case:

1. The signatures are completely different, although each inputs are from the identical tackle.
2. The public secret’s equivalent for each inputs, as anticipated.

This means that the signature will not be for all the transaction however fairly for every enter individually. Evidently every enter indicators a selected “message”.

Questions:

1. Why are the signatures completely different for every enter inside the similar transaction?
2. Does this imply {that a} signature will not be generated for all the transaction however fairly for every enter independently?
3. What precisely is being signed in every enter, and what position does UTXO play on this course of? Does the signature have a reference ultimately a SPECIFIC UTXO?
4. Why is the Witness knowledge solely represented by hex binary? I could not discover any converter to “human” Script directions. Is there any?
5. So mainly, is it right to say that, for a similar tackle, the locking script would be the similar, whereas the unlocking script (witness) will likely be completely different as a result of it rely upon the SPECIFIC SINGLE INPUT of a transaction?

Any clarification on this habits and the underlying mechanisms can be tremendously appreciated. Thanks!
