Ambiguity in description of .NET regular expression source generators

[SetTrend]

In section Source generation, the documentation states:

The generated implementation of AbcOrDefGeneratedRegex() similarly caches a singleton Regex instance, so no additional caching is needed to consume code.

… but right below that you're providing a screenshot that's manually caching the generated RegEx() result in user code:

What's true? — Do we need to cache the result in a static readonly variable or can we call RegEx() repeatedly without penalty to runtime execution time?
