My error. I wanted only say that sometime a series value is indipendent from
index (3 or 100 after tail is the same).

You should read my observation in the context of thread with Mecir. The sense
was: if we leave changing the serie, to get the sameness of the value of a
word, what
happens when I change binding?

I wanted to remain near the literal expression of EQ in the text of Mecir to
define Identical? I did not want to change the expression "get/any 'a".

Do you think that when one changes the Binding of a word, Rebol delete the old
word and creates a newer one? I think it change only a propriety of a word,
leaving the rest the same.
