can you give us more information about how everything is currently setup, or what your ultimate goal is? Attack a file too if possible...

If the local rotation axis is suddenly different after you create the spline ik that is due to the spine being curved, if the spine is verticle then no "pre-twist" will occur. The more cuved the spine the more severe the pre-twist occurs. This is a problem I have noticed in rigging and as a result it makes it hard to figure out the correct advanced twist settings. I'd have to see how you made the character or a copy of the file to really help you but I get the feeling this is what you are experiencing.

I maybe incorrect, I'm new to Maya advanced rigging. It may have something to specifically to do with LRA of the controllers "up" axis not being the same as the bones LRA when the advanced twist control is applied. I think they flip, or mabye if you use controllers written in instead of cluster selection handles.
