Why does the man need to build the second fire

Basically because he is wet. The man's foot breaks through some thin ice in the creek. It is so cold outside that the man has no choice but to light a fire and dry out. If he did not, hypothermia would set in within a few minutes. He would also lose his foot.

I thought it was because he built it under a spruce tree thinking having the advantage to pull twigs and such for the fire making it easier to pull witched caused agitation to the tree causing a load of snow descended upon the man and fire which blotted out the fire.please correct me if im wrong
