The literal answer is because -a does a search of the command hash table
keys, and command full paths are values, not keys.

The more descriptive answer is because -a is supposed to mean a path
search for the argument, and the string "/usr/bin/zsh" is not the name
(as in, last path element) of a file found in a directory in $path.
