It'll actually cause the strands to break faster if it's not twisted. Best to have a bit of the solder creep a millimeter or two under the insulation, it will provide better strain relief than having exposed strands that aren't supported.
One thing I'll point out, when you solder stranded wire (and unstranded solid conductor) it actually changes the temper of the metal itself, but is still much more reliable than the 'butterfly' type crimp, found on the Tamiya connectors, it cuts the strands when crimped.
