    Hello! Let’s consider the following snippet from [1]Bash docs:

    It is written that: Each pattern undergoes tilde expansion, parameter
    expansion, command substitution, and arithmetic expansion. But if it’s
    true why the following code outputs Y?

You're right; case patterns undergo quote removal.
