bash                        5.1 patch 016 -> 5.2 patch 7   https://www.gnu.org/software/bash/bash.html                                
bash                        5.1 patch 016 -> 5.2 patch 8   https://www.gnu.org/software/bash/bash.html                                
bash                        5.1 patch 016 -> 5.2 patch 9   https://www.gnu.org/software/bash/bash.html                                

The results reported by ./xbps-src update-check bash meanwhile are:

bash-5.1 patch 016 -> bash-5.2
bash-5.1 patch 016 -> bash-5.2 patch 1
bash-5.1 patch 016 -> bash-5.2 patch 2
bash-5.1 patch 016 -> bash-5.2 patch 3
bash-5.1 patch 016 -> bash-5.2 patch 4
bash-5.1 patch 016 -> bash-5.2 patch 5
bash-5.1 patch 016 -> bash-5.2 patch 6
bash-5.1 patch 016 -> bash-5.2 patch 7
bash-5.1 patch 016 -> bash-5.2 patch 8
bash-5.1 patch 016 -> bash-5.2 patch 9
bash-5.1 patch 016 -> bash-5.2 patch 10
bash-5.1 patch 016 -> bash-5.2 patch 11
bash-5.1 patch 016 -> bash-5.2 patch 12
bash-5.1 patch 016 -> bash-5.2 patch 13
bash-5.1 patch 016 -> bash-5.2 patch 14
bash-5.1 patch 016 -> bash-5.2 patch 15

Needless to say, the ordering of ./xbps-src update-check bash is much more sensible.
