Here you try to end the volta-spanner:
>  \set Score.repeatCommands = #'((volta #f))
>
Here you try to begin a new volta-spanner:

Both commands are set at the same musical moment, conflict! So Lily
tries to makes any sense of your input and throws a warning.

`repeatCommands' expects a list. So put all stuff in _one_ list:

\relative {
 c'1
 \set Score.repeatCommands = #'((volta "1"))
 d'1
 \set Score.repeatCommands = #'((volta #f) (volta "2") end-repeat)
 f1
 \set Score.repeatCommands = #'((volta #f))
}

As shown in the NR ;)
