Any regression is just a form of correaltional analysis (and does not imply causality in general).

In my view, svy: y x (or the other way around) is especially appropriate in case of within-correlation in panels to avoid inflation of standard errors that would occur in case of using a simple correlation command. 
Make sure you et the options right.
