It does seem so, doesn't it?
Does the wood come laminated and tapered already? If not, I'd follow Pat's advice. Make either the cherry or the cedar into backed board bows first. Practice tiller on these.
People do laminated bows because some woods are really strong in compression (belly woods) while others are strong in tension (for backing.) Light weight brittle woods (like cedar) are also good as middle lamination as they keep the moving mass low (more energy is imparted to the arrow instead of moving heavy limbs.) Cherry and cedar are both belly wood = no advantage in laminating them as they will need backing anyway. You could use glass for backing but I don't know if either of these woods are strong enough to take that, I never tried it, and silk backing is so much easier to apply.
If you are building a glass bow, it doesn't matter which wood you use. The glass backing and belly do all the work, the wood is mainly for show. But with a glass bow, all the laminations (glass and wood) need to be pre-tapered very precisely before you glue up as there is almost nothing you can do about tiller after the glue is dry.
