In this particular case it's almost exactly the same, but in general it won't, and you'll have to repeat steps 6 to 9 with an appropriately adjusted value of drift, and do so until the value of drift at Step 8 matches the one used at Step 6.
If you stop at the first iteration, you might get the heading wrong by even 10°, which is probably enough to fail the question, if not the actual navigation. Try with TR/GS = 300°/80 kt and W/V = 160°/40 kt, to see what I mean.

is answer for the above heading-265degrees and TAS- 59Kts?
Just done it using wind down method and it took a lot of adjusting and fiddling about to do that one.
