New "X" License Purchase Needed every year?

Hi there,
I was sent an email from Envato Market to extend my support for 12 months. The only option to do so after clicking the link in my email was to purchase the license for X again. I did end up re-purchasing the license along with the extended support. However, my question is whether I needed to buy a new license.
I look forward to clarification on this matter.

Hi There,

No, X license is valid for a lifetime.

We are really grateful if you purchase extended support.

But if you face issues paying for it, you do not need to buy a new X, we will assist you always with any theme related issues.

Hope it clarifies
