It really shouldn't be doing that. Grub shouldn't be doing any writes at 
all during boot (unless you're using some of the more exotic commands or 
save_env) and the raid code specifically errors on writes to it.

If it was linux I'd expect both drives to be wrong unless there is 
something silly in the init scripts.

When you say it fixes it, is that a full re-sync or something else? 
Could you check the superblocks? In grub use the following on each 
device for 1.2 arrays.

hexdump -s 4096 -n 256 (dev,p)
