[racket] planet/scribble and versions

Are the macros for PLaneT package specs in "planet/scribble" correct?

I haven't traced the code thoroughly, but if the output of 
"syntax-source-planet-package-symbol" will be used as-is for actual 
"require" during Scribble formatting... won't the ":MAJOR:MINOR" (not 
":MAJOR:=MINOR") version let Scribble use a different version than the 
version that the ".scrbl" being formatted is coming from?

I'm asking because McFly currently makes ":MAJOR:=MINOR" version 
references itself right now, but I just saw the current advice in the 
documentation is to let the "planet/scribble" module do the PLaneT 
package self-references for you:
