It certainly does. From the documentation of setAs():
With this explanation as background, the function setAs does a fairly
obvious computation: It constructs and sets a method for the function
coerce with signature c(from, to), using the def argument to define the
body of the method.

No cheating seems needed. The setAs() call is part of your software &
presumably you document it somewhere. You do have to construct the
corresponding alias in the same .Rd file, but it doesn't amount to cheating.
It's true that a user would have to be unusually well-informed to know
how to ask for the corresponding documentation explicitly.
