can it be changed?

fsck checks in sequence all filesystems with 6-th field in /etc/fstab 
equal 1, and in parallel all with 6-th field equal 2 but one process per 
disk.

This is right if you have magnetic disks. checking 2 partitions in 
parallel on one physical disk is bad idea.

But it is very good idea to do this on SSD with multiple partitions.

Can it be changed ?

If not - i can write a fix for this (option settable in fstab).
