Right; the "reason for it" is that you implicitly asked zsh to attempt
expansion before completion.

} if I remember correctly, most people said that one sometimes want to
} complete after a parameter expansion, but almost never after a command 
} substitution.

The problem with completing after a command substitution is that it has
to actually execute the command to figure out what to complete.  There's
no way to predict the side effects of executing the command multiple
times (at least twice -- once when completing and once when executing
the whole command line) so it's better to never start down the road.

Dunno if this is frequently-asked enough to be worthy of a FAQ entry ...
