Certainly possible, but for practical purposes that would require the 
authors to declare the "dual-license" approach up front.  After a lot of 
changes are made, or many programmers contribute, getting those 
permissions would be troublesome.  It would certainly be better if the 
GPLv3 project authors recognized the Apache heritage of the code and took 
the affirmative steps to make sure that changes were available to Apache. 
I'm not sure that will happen.

AIUI, the fora in which patches are submitted include the requirement that 
the code be submitted under ASLv2.  Which is fine, as long as the 
submitter has the appropriate rights to do so.

Depends on how thorough they are, but you are right, if they are 
completely accurate they would change the license references to GPLv3. 
Note that they still need to comply with the Apache license requirement to 
include a copy of the ASLv2 in the distribution.
