How can a 128-bit sequence be more secure than a 256-bit sequence?

The key you’re going to use is 128-bit.

I’m not a cryptographer but my understanding is your actual bitcoin private key is 128-bits. So using a 24 word phrase that generates a 128-bit key anyway is unnecessary complexity.

The amount of words are dependent on the amount of bit-chunks: for each 11-bit chunk, a corresponding word is selected.
