Yeah, this is correct. I believe Mozilla's intent is to share the JIT
between Mozilla's javascript and Adobe's ActionScript compiler;
Mozilla gets a much faster JIT and presumably Adobe gets better
standards compliance and more feature development.

Frank Hecker from Mozilla goes into it pretty in depth here:

Not clear to me what the AJE/javascript relationship will be going
forward- if moz will adopt AJE and dump javascript, or adopt AJE and
keep javascript, or they'll just share the JIT, or what.

Way, way different, though to be fair, with MS pushing XAML hard,
Adobe's revenue potential from anything other than tools is zero, so
with proper licensing, the revenue lost by open-sourcing flash would
likely be low.
