That sounds a little strange. Usually when you adjust the bridge angle, E, A, and G strings' intonations are most sensitive. I guess you can check if both of your posts are the same height. You can do taht by measuring the action on the low E string and the action on the high E string and compare the two. I'm not all that sure if the spring configuration in the back matters but its a good idea to keep it symmetric. You can also look at the angle of the bridge from top and from bottom (the two side of the bridge and how they look against the line of the body). In any case, i wouldn't worry too much about it. Just reintonate the ones that are out of wack and you'll be all set.
