When using an end mill to cut a slot the same width as the cutter, one side of the slot is being cut 'conventionally' and the other is 'climb milling'
There is also a tendency to re-cut the chips that have already been removed, which can put the cutter off line if it is slender.
As has been said, best to cut a central undersized slot, then shave the edges to finished size. (Preferably using climb milling if your machine is rigid enough)
