The off beat slide involves picking a bass note and the first note of the slide together. This pinch is on a beat of the bar but the left hand finger that is fretting the string moves to the desired fret on the following off beat. In the following example a pattern is played over an A chord. The second bar is similar except a slide is played. On the first beat of this bar move the A chord shape back one fret and pinch the 5th and 2nd string together. Slide the entire shape up to the normal A position on the + immediately after the first beat. It is important to let the first note sound for a half a beat before sliding precisely on the +.
