It sounds like this will automatically find and associate with each commit that last touched the modified lines, which is nice. There've been plenty of times I haven't done a fixup because I couldn't be arsed to check exactly which of the three ancestor commits in my branch the tweak actually belongs with. I wouldn't even consider splitting into three fixups if there were three tweaks that belonged to three different ancestors. It sounds like this tool/workflow will do all that work with a single invocation.
