wp_GetMonitorAt(...), which is used by these functions uses system call "SysGet" to get monitor info.
This information is provided by Windows.
It seems however that the order/numbering of these monitors are reported is not necesarily the same as what is shown in "Display Settings".

numbering used by SysGet is based on the order the monitors are enumerated by EnumDisplayMonitors.

EnumDisplayMonitors is a function provided by Windows. AutoHotkey provides it with the address of its own function, and it calls the function once for each active display monitor.

windows display control panel is not always numbering the monitors in the same order as they are enumerated in this method.
