That's incorrect - they can put 8 player instances into an otherwise 4 player roulette, as guildhests have shown. The level 40 guildhest is a 8 man instance, whereas all other guildhests are 4 and you "can" get the 8 one on your roulette.

So a limitation seems unlikely. It probably has to do more with reward balancing or...something. Honestly, I don't get it.
