The origin of the dq effect isn't that all the spins are coupled, but that both the Me and H2 spins are independently coupled to H3 (i.e Me <-> H3 <-> H2). so you wouldn't expect the same effect to give rise to complex fine structure for the methyl group and H2, but, these peaks may have fine structure from other effects.You'd have to take a close look at the spectrum you have. The C2 H will have a strong coupling to the C3 H, and may also have a weak coupling to C4 (making it a doublet of doublets, dd), but the long distance coupling will be weak, and whether you see it or not will be dependent on field strength.
PS. and while we're brushing up on NMR, the peak i posted before also is a good example of second order effects - note the deviation in intensity from the expected 1:2:2:1:1:2:2:1 pattern for a dq.
