C64 User port expander: may it work with Plussy?

Dear HW gurus!
There is an ebay part, I found really interesting Scanntronic part for my future projects, just found it by accident 10 minutes before. This is a C64 User port multiplier, and as I see no switch, probably all three can work at the same time (up to the User port amper limitation, I suppose)

As the VCC and GND are at the same place on the C64 and Plus/4 User ports (and I find mor and more similarities), do you think, this user port multiplexer may work with Plus/4 too without damaging anything?
Or if not, why not?

I have less than 1 day to decide. Please help me, and many thanks in advance
