This looks like it may be a bug. I found the following:
"If a class contains accessor functions with different access control namespace
attributes, (for example, a protected setter and a public getter) using one of
them causes a compile-time-error, for example, Compiler-Error 1000: Ambiguous
reference to myVar".
Your getter function is in namespace InterfaceA and your setter is in namespace
InterfaceB.
The workaround is to rename your getter or setter function to avoid the
mismatch.
So, instead of creating set/get methods, create setData and getData methods.
You will need to call them slightly differently but it does work...
var impl1:ImplementationClass = new ImplementationClass();
var implA:InterfaceA = InterfaceA(impl1);
var implB:InterfaceB = InterfaceB(impl1);
implB.setdata("Something");
trace(implA.getdata());
