a bug in relion-3.1.3/src/acc/cuda/cuda_kernels/helper.cuh:932 & has lower precedence than !=; != will be evaluated first

if((x ^ y ^ z)&1 != 0) { img_in[pixel].x = -1; img_in[pixel].y = -1; } (the same as ver4.0)

I dont know why use " if((x ^ y ^ z)&1 != 0)", maybe it just like "if((x ^ y ^ z)& true)", Is it a mistake or something I cant understand?
