Because all indication is that is where they are headed.
They have hinted that the N8 isn't their new flagship, and that MeeGo devices will be announced by the end of the year. They have also started using the term "superphone," apparently recognizing that the "smartphone/featurephone" distinction is being blurred as technology advances.
As Android is starting to move to the midmarket, Nokia is looking to move further downmarket with Symbian (mostly with the aging Symbian^1).
While there will be some commonality between Symbian^4 and MeeGo because of the commong QT platform, note that it will be a stretch to think that Nokia's Symbian^1 positioning at the low end really plays into that strategy. Symbian^4 is yet another compatibility break (with Symbian^3 being the temporary bridge), as it relies on QT. However, Symbian^4 (and Symbian^3 for that matter) will not run on devices like the 5250, at least for the foreseeable future.
With the common development platform, plus MeeGo's Linux underpinnings (better suited to the "superphones" and tablet devices to compete with the likely iOS devices) it becomes difficult to see what Symbian^4's role is long term.
Rafe suggests as much with his earlier comments about how the Symbian/MeeGo split is appearing "shrewd" (if, IMO, somewhat accidental). Clearly, Symbian is optimized for lower-end hardware, while MeeGo is better suited to the newer devices down the pipeline with dual core processors and lots of RAM. Symbian was never intended for such powerful devices, so it makes more sense for Nokia to go in a different direction. Given how long it has taken for Symbian to evolve into the touch device market (recall the early announcements were made shortly after the original iPhone debuted), it's clear that it has proven more difficult to adapt than anticipated.
Surely Nokia would rather have had an OS like Symbian^3 a year or even two years ago, with Symbian^4 coming out now. But they didn't. They are now finally entering Q4-10 with an OS that addresses consumer perception that Symbian was behind Android and iOS.
Nokia's semi-retraction of its earlier intimation that future N-series devices would be MeeGo-only seems more like a temporary reaction to avoid scaring developers away. They need developers to embrace Symbian^3 and Symbian^4 since that will be their bread and butter until MeeGo hits the mainstream. Long term, it seems pretty clear that Nokia sees MeeGo as their ticket back to preeminence at the high end.
