JPJP: It's intentionally written that way because not all B737's have LNAV available as a (pre-)armed mode, i.e. prior to initiating a go-around, and therein require that the roll mode is 'selected', and accordingly it is hoped that those whom fly those types might still find this 'generic' advice useful too...of course in the NG it's pre-armed, though always assuming that the missed approach is indeed available (programmed) in the FMC via ones navigation performance engineering department and an example where it wouldn't be, being an airfield which has not been pre-programmed into your FMC in terms of approach & missed-approach tracks (& vertical profiles), i.e. just the 'blue circle' and nothing else and / or maybe not even the blue circle?!
