Two names for one type of items

There are two names for the log items (for example Oak Log, Acacia Log): "minecraft:log" and "minecraft:log2". "/setblock ~~~ minecraft:log2" places Acacia Log, then Dark Oak Log (when typed 1 after "minecraft:log2"). "/setblock ~~~ minecraft:log" places all types of wood, horizontally and vertically (depends on number after item name) except Acacia Log and Dark Oak Log.
