When I said they will re-calculate your score at e-APR, I literally meant it. Your qualifications at the time of e-APR. You will even see your points again when you submit your e-APR. Like I said, you will get credit for 2 years if you submit your e-APR after the completion of 2 years of work experience.
So, it's literally up to you now. As per my understanding, you will get 2 years of work experience after June 26th. If you submit before it, the recalculated score will be 434 which will result in refusal. If you submit it after June 26th, you will get credit for the two years and your score at e-APR will be 459 which means your application will not be refused.
Personally, I would not recommend you to waste this ITA or jeopardize your chance of getting PR in Canada. If you are still in doubt, an immigration lawyer (a good one) will be able to help you. She/he will suggest the same.
