Sole manipulator of the flight controls does not require you to be PIC, just licensed, or rated or certified on the type or class of aircraft being used.
Further more unless this fellow has a validation from the Sri-Lankan authorities allowing him to be the PIC of a Sri-Lankan registered aircraft, he may not log anything as PIC. It wouldn't matter if the instructor pilot agreed with who was acting PIC or not. Hope this is clear because the law very much isn't, especially when we deal with international multi license and registration issues!
