Is it correct that in Japan Prof. Rowan REQUIRES shuffle is no cards left in hand?

ナナカマドはかせ
自分の手札を1枚選び、残りの手札をすべて山札にもどす。その後、山札を切ってから、山札からカードを4枚引く。
（自分の手札がこのカード1枚だけなら、このカードは使えない。）

my translation

Professor Rowan
Choose 1 card in your hand and back the rest of your cards into your deck.
Then shuffle your deck and draw 4 cards.
(If this is the only card in your hand, you can't play this card.)

In japan. Shuffle is must.

Japanse "ナナカマドはかせ" and English "Professor Rowan" is another one?

Q. If I only have two cards in my hand and play Professor Rowan then I keep the one remaining card in my hand, but do I shuffle my deck or not (since I put zero cards from my hand into it)?
A. Shuffling is a must when playing Professor Rowan regardless of whether you put any cards back into your deck or not. (Apr 3, 2008 PUI Rules Team)
