Yes, right now it does. But that won't necessarily always be the case.
WotC's plans in this regard have changed slightly over time...
The best answer in the whole thread! Thanks for posting truth rather than half-remembered speculation.
The last word from WotC on this is that at some future point you won't be able to access back issues from outside of your subscription . . . . I'm really hoping they change their minds on this one . . .
Going from the current model from where you get everything to a future model where there are limits is just asking for trouble and upset current and prospective customers. Besides, all the crunchy bits will be in the Compendium and Character Builder anyway, so why place limits on the magazines?
Besides, as Ruin Explorer pointed out, if they want this to succeed they need to focus on excellent service and awesome new content every month. Wasting time with limits on past content is a very bad idea and could hurt DDI's ability to succeed.
If the new monthly content (the mags, basically) start to become mediocre, then more people will try to find a way to get it cheaper/free/unethically (or just ignore it entirely). If the magazine content instead becomes stellar and a major selling point every month, then only a small handful of cheapasses will try to circumvent the system and WotC should have plenty of eager subscribers willing to pony up a monthly fee.
I don't see this actually becoming an issue until the Visualizer and Game Table have launched hopefully sometime next year and WotC has checked off the "higher priorities" than messing with the back issue situation. By then the customer base will be used to roughly a year's worth (give or take) of no "DRM" hassles (cause that's essentially what we're talking about, is a form of DRM).
