Hmm, not sure about the demo but I know the real version works fine, it's supposed to prompt you if you want to hold the old textures or replace them with the ones in the original file. Not sure about poser objects though, maybe that has something to do with it, might work differently than with other model formats. I can't test it as I don't have Poser and Vue 4 Pro on the same machine (home vs. work). You might post it to tech support, maybe it's a bug in the demo??
