GX24q-2 is for use on 18W Triple compact fluorescent lamp.

GX24q-3 is for use on 26 or 32W Triple compact fluorescent lamps.

I think it is there to ensure the correct bulb size gets installed with the correct ballast
Yes, The tabs prevent the insertion of the wrong lamp on the wrong base. The 18W lamp has a different filament than the 26 and 32W (which use the same filament) and so the ballast required for operation is different.
If you operate a 32W triple tube lamp with a ballast designed for an 18W triple tube lamp you would not get the specified performance of light and life (plus you would void any warranty).
