But read for yourself.
That's the way I implemented it. Unless someone changed it, the documentation is correct. Someone might think now it'd be at least handy to have a mechanism to enforce parsing of all expressions and queries for debugging purposes. But that's not that easy. As soon as you use for example a record variable, each reference to one of the result row columns is of unknown datatype until that query is actually executed. You cannot parse an SQL query with unknown parameters via SPI.
