The following is a lot oversimplified, but:

It's read one character at a time and each character is then metafied
before being aggregated into the string buffer.

It's more like having a bag of popcorn; they don't all pop at the same
time, but ideally you don't open the bag until all of them have.

History isn't stored until after bangchar references have been expanded, 
so although it's closer to literal it's still not the actual input line.

Partly this is from separating ZLE into a module years after the shell
was first written.  It's designed so that somebody else could write and

It works for me:

torch% echo hello
echo hello
hello

Are you sure that you're actually executing the correct binary when you
are running interactively?  Maybe a startup file is "exec"-ing another
path?  What happens if you start zsh with the -v option?
