Why are these powerline adapters limited to just 4 concurrent devices?

Hello all,

i am looking at buying 3 pairs of TRENDnet TPL-308E2K powerline adapters as the reviews are good and I have had great success with other powerline adapters in the past. the great thing about this particular model is that it seems very cheap indeed.

What is putting me off and I don't understand is why the manual states that a maximum of 4 devices can be used together when for other adapters it usually states as many as you want.

Can anyone explain?
