Name proliferation is a famous issue. One-use names are evil.

I disagree. Names are comments. You don't want more mutable state across large scopes, but using intermediate names can help comprehension.

why ? Could you elaborate ?

Because from my point of view, it could be only the case only if the scopes are weak or underused, or names are bad (too short, ect). After SSA is all about one-use names.
