This summary is not the rule. The rule text controls.
Here's a plain English summary of this rule:
If you're suing someone (or being sued and want to fight back), you don't have to file separate cases for each problem you have with that person. You can bundle all your claims against them into one case, even if the claims are not related to each other.
This applies whether you're the one starting the lawsuit, filing a counterclaim against someone who sued you, bringing in another party, or making a claim against a co-defendant. You can list out as many separate claims as you actually have. You can also list claims as backup options to each other, meaning you can say "I want this, but if I can't get that, then I want this instead."
For people going through small claims or civil court without a lawyer, this rule just means you can handle multiple disputes with the same person in a single case, instead of filing paperwork and paying fees over and over again for each issue.
