The new wording doesn't make sense; a mask doesn't set itself.  I would
suggest:

"The coherent mask can always be set to the same or a smaller mask than
the streaming mask."

Yes, the original sentence is not particularly good, but I think even
your modified version can be interpreted as "a mask setting itself"
for all the same reasons that the original can be (which mask does "same"
refer to?)

Even so, I prefer your version.  Thanks. :)
