I cannot think of how that would apply in my circumstances. My "old" card would theoretically have been a LAN OW Ruby which wouldn't entitle me to access. I say theoretically because LAN never sent me it. So my new card that entitled me to lounge access is the only one I ever got.

My "new" Emerald card that I may or may not get in August doesn't make much difference over my "current" card in terms of lounges, only gives me access to First Class lounges, whether I will go to one and whether it will be honoured on my current card is anyone's guess.

I'm not really a lounge fan, I want the upgrades and the bonus miles, so in that respect, having a new Emerald card over having my current Sapphire one doesn't make much difference. Which is lucky, because I am unlikely to receive it in a timely manner.
