[dcl.fct.def.coroutine]: Initialization of the copy of a parameter of a coroutine

[dcl.fct.def.coroutine] paragraph 13 states the following:

When a coroutine is invoked, after initializing its parameters ([expr.call]), a copy is created for each coroutine parameter. For a parameter of type cv T, the copy is a variable of type cv T with automatic storage duration that is direct-initialized from an xvalue of type T referring to the parameter. [...]

Considering the following coroutine:

task<void> f(int& p)
{
   ...
}

the copy of the parameter p has type int& and it is initialized with an xvalue, which should not be legal.

Is there something else that I might be missing?

Thank you!

Start with [dcl.fct.def.coroutine] paragraph 13, then compare its wording with the parameter initialization rules referenced by [expr.call]. Determine whether the wording correctly covers a reference parameter such as int& p; done means resolving the question with clarified standard wording or an accepted explanation.
