An often missed step in the process for sure. Pressing the cork (cork corks) into the bottle compresses the air in that little space. Left standing, the pressure will dissipate thru the cork. If you lay the bottle on it's side right away, that pressure will be trying to force wine thru the cork. It really is of no detriment since newer synthetic corks are impermeable. You might see an effect on an older/cheaper corkI wouldn't worry about that too much. Is it just this one bottle, or have you seen it on several? Did you keep the bottles upright for a day or two after corking? I've had this happen simply because I laid them down too early and the corks hadn't fully re-expanded.
