RAW: It would work
The statement is:
when you are wielding in one hand and no other weapon
It doesn't say; "in just one hand". Different statements. If you are wielding in two you are wielding in one, but not only in that one. If I ask you when you are wielding that weapon in two hands: What are you wielding in your left hand? Your answer would be: a sword. If you weren't wielding in one hand you wouldn't be in two, that would be impossible. You wield in one AND in the other, both hands are wielding.
If a carriage is being pulled by 2 horses, horse "A" and horse "B", by themselves they would not be able to pull, but together they are. The horse "A" is in fact pulling the carriage, as the horse "B" is. If horse "A" is pulling, the carriage is being pulled by horse "A", once horse "A" is 1 horse, the carriage is being pulled by one horse. Using the same logic to "Hands" and "Wielding" my point above is proved.
