Crankcase bolts

Evening all,
I've just assembled the crankcase on my Z900 A4. It all appeared to go well although I wasn't quite sure how far to extend the sealant on the flanges but just applied common sense. Strangely no manual seems to cover this in any detail. Anyway, there was an instruction to apply threadlock and sealant to the two outer (main crankshaft) 8mm bolts (numbers 6 and 8 in the tightening sequence) but not 5 and 7? I couldn't see why 6 and 8 needed sealing but not required for the two forward set bolts 5 and 7. I would be grateful if anyone could let me know.

Is it because the two that require sealing, their threaded holes break into an oil gallery, whereas the two that do not require sealing go into blind holes ?
Or something like that anyway ! :D
Someone will know for certain & be along shortly no doubt !!
