What does all subsequent releases mean

Example 1:

• A fix lists as "9.3RC1 and all subsequent releases" - means that it is also fixed in 9.4, 9.5, 9.6  all the way to the current release. 
• In this case no 9.2Px release has the fix

Example 2:

• In this example all releases higher than 9.15.1 have the fix. for example: 9.16.1 
• Also 9.14.1P2 to 9.14P4 as well as 9.13.1P9 and 9.12.1P12 have the fix
• New fix releases for the releases prior to 9.15.1 will get added as they become available
