My understanding, such as it is, is that if you overexpose the highlights to the extent that detail is lost (blown) then even in RAW you have lost it although RAW has a little more leeway than JPEG. Better to expose for the highlights and get them right and sort out the shadows if necessary as they are much more rescue-able. Even here if the exposure is too far out then rescued shadows will exhibit noise.
In other words you have got away with it so far but better to get it right in camera! So easy to forget to change settings back.
