Are you saying that your license allows GPL-forking?
No, I am saying that the Apache License says:
You may add Your own copyright statement to Your modifications and may provide additional or different license terms and conditions for use, reproduction, or distribution of Your modifications, or for any such Derivative Works as a whole, provided Your use, reproduction, and distribution of the Work otherwise complies with the conditions stated in this License.
Note that our license applies to the Work, not the copyright on the derivative work, and thus any GPL code combined with Apache License code will remain under the GPL.
