AFAICS according to ISO your program is "implementation dependent".
Namely, you are not allowed to simultaneuosy use two variants.
It is implementation dependent if access to component is done
before assignment proper or if there is overlap.

GNU Pascal passess your construct without any special treatment
to the backend.  I believe that backend first evaluates component
and only later is doing assignment, so it should work.
