NOTE : Microsoft IS listing the 24H2 and 25H2 as the same

Yes, it's the same update for 24h2 and 25h2, and the same for the following ones.

 

[garlin]

22H2 & 23H2 share the same CU's, it's the same base Windows outside of installing the 23H2 Enablement Package.
24H2 & 25H2 share the same CU's, it's the same thing only with the 25H2 EP.
