Yep, that's what the report notes too :)

So UK has 2.3 time less official unemployment on this age group (3.6% vs 8.5%). All of this with only 1.5% more employed people. This is to say about all of the difference in unemployment comes from the UK government convincing people they're inactive and not unemployed (in various ways) whereas the FR government wasn't as successful at this game. 1-0 for Blair. See the "willing to work" figure below for the so-called "inactive".
