I think it does: HLY numbers in the east rose at the same time they fell in the west. (There's no pre-2003 data for these countries, of course, so we're missing part of the trend, but the pattern agrees with my hypothesis.)
But in looking at the data in more detail, there's another issue I noticed: it appears that Eurostat changed its method for calculating HLY in 2004! If so, that would make comparison before and after the switch impossible.
