You know, I hate that they are off as well but I have been focused on other things of late. Next update will fix this.
For now, I can tell you 2 things. the bug was introduced with the fix for the weird scaling stuff that Blender .28 was doing a while back.
It may be enough to either rotate the bone within the metarig edit mode before generating the rig - and/or manually change the axis of the super finger settings, which is set on the metacarpal bone of the metarig.
In terms of usage, it is actually really important that they work the same or you won’t be able to Paste Opposite poses, which is something I do a lot of and encourage everyone to do often. So I’ll be patching this as time permits.
