I think that would be correct, because the rprompt is printed last and

Some people want the entire command line to look one way and the output
from the command to look another way, so they can easily tell what's a
command and what isn't when scrolling backward through buffered output.
Leaving effects turned on after the prompt is the only way to do that;
at some point it was decided that it was better to have the prompt help
out with it, than to force people to trick the shell into outputting a
terminal control sequence without using the prompt escapes.
