That is setting a property, not a variable.

Properties *are* shared between threadgroups - they are global to the
JVM, so there must be an error in the test plan.

No, it evaluates the property named parameterName - properties are not
the same as variables in JMeter:

Must be a bug in the test plan

I assume you mean propertyName.

Yes, it is.

Which will set the property "securityid" to the value "bsh.args[0]"
and return the value "bsh.args[0[".
If this is executed in a BeanShell script, the script will see the
value of the function call - i.e. "bsh.args[0]" - which is a BeanShell
variable that is defined if the parameter is defined.
So the script:
print(${__setProperty(securityid,bsh.args[0],true)});
is passed to BeanShell as
print(bsh.args[0]);

Looks OK; it will return "bsh.args[0]".
