You're basically correct, yes, it's an abbreviation.  Not entirely
logically, it's allowed by the SHORT_LOOPS option.

% if [[ -n string ]] echo string is stringy
string is stringy
% setopt noshortloops
% if [[ -n string ]] echo string is stringy
zsh: parse error near `echo'
% 

If you want to be purist you can turn that off, although of course it
does have other consequences.
