It did mention autoconfigured in the text, but the below makes it more obvious.

More clearly document IPv6 max_addresses parameter.

max_addresses - INTEGER
Number of maximum addresses per interface. 0 disables limitation.
It is recommended not set too large value (or 0) because it would
be too easy way to crash kernel to allow to create too much of
autoconfigured addresses.
Maximum number of autoconfigured addresses per interface. Setting
to zero disables the limitation. It is not recommended to set this
value too large (or to zero) because it would be an easy way to
crash the kernel by allowing too many addresses to be created.
Default: 16
