Yes, before the skin is printed.

It's the *outer* quotes (which wrap the whole string), not the inner quotes 
parts of the string. Inside 'single' outer quotes, $variables are not expanded 
and need not to be escaped; inside "double" outer quotes variables are 
expanded (replaced with their values) if the $ is not escaped by \$.
