Check Understanding: `(and ...)` Does Not Behave Logically Inside `(or ...)` - always `true`

[mentaloid]

According to Datomic Queries:

If no bindings are provided, the function is presumed to be a predicate returning a truth value: null and false are treated as false, anything else is treated as true.

Expression clauses do not nest
Instead, multi-step calculations must be performed with separate expressions

So this is by design.
