Not sure how to answer - Habs Boys Maths 2014

Hello, DD completed this paper yesterday and DH and she disagree about the answer to the following:
Question 2
In the winter, I try and climb up an icy slope starting at the bottom. Each time I
make a move I find that I go up four metres but then slide back down two metres.
How many moves do I need to get to the top which is 8 metres up the slope from
the bottom?
___________
DH says that because you would have reached the top at move 3, even though you would then slip back 2 metres. DD says 4 moves to actually reach and stay at the top. Who is right? Suggestions,please!
Thanks.
