I remember years ago, a friend of mine who was a pretty solid player always seemed to bend sharp. He was in a band with a guy who always bend pitch/note perfect. One was too much and the other was not enough.
In a way, Think think bending is the general understanding that the bend should land on pitch but, as EVH said: 'Gotta learn the rules before you break them'.
Bending is feel. Bending is often the element of a guitar that makes it the most voice-like.
Back to my start above; play and don't think so much. Antithetical to a teaching site? Perhaps. However, you have to feel the bend and not think it. I'm guessing our friends in Skynyrd weren't thinking about it so much.
