Correct. :-)
That's exactly why we switch from a single rules file to a directory of
rules file. Users should have defined their own rules in a file read
*after* 50-default.rules, so something like 90-mysetup.rules, as
explained in /etc/udev/rules.d/README :

"The files which name ends in ".rules" will be read by udev in lexical
order.
Any others will be ignored.
There are some example rules in rules.examples, take a look at those for
an idea of what's possible with udev.

When a rule matches in one file, a different rule in another file will
be
ignored, so be sure to name your own files properly.

Be sure to leave 50-default.rules as it is, so the spell can update it
when needed."

I think that is clear enough ? :-)
