[Superman] Does Superman's disguise work?

I had this conversation with a few friends the other day and I supported that it does actually work under the correct circumstances. I will post my explanation  here and I want to hear your opinions as well:


The way this works is if the individual has 2 personas. It's absolutely necessary one of the personas to be extremely more famous than the other. 

Example:

Let's say one as said above has 2 personas. One of them is a world famous chef and the other is an IT student (let's call him Matt). 
Obviously everyone have seen the chef (on TV etc.) but they know Matt and his background and he does not have any indications of being a famous chef and he of course denies it. So they think its just a coincidence.

Now if someone who knows the chef personally just happens to be walking around the city and sees Matt with his friends immediately they (the friend of the chef) will go up to him and recognise him as the chef because they are only aware of the existence of 1 person with that face not multiple.

Christopher Reeve was able to go around without being recognized after he played Superman in a movie. He put on a suit that was a bit too loose, slouched a bit, and he wore glasses. 

Simpler disguises have worked. Terry Pratchett just took his hat off to go from being recognized as a famous author to being unnoticed as a bald man with a beard. 

Superman could disguise himself fairly easily because everyone knows his real name is Kal-El, he lives in a fortress in the Arctic, and he always dresses the same way. Nobody looks for Superman in disguise because his identity is public knowledge.
