Account for what? What you have described is a fundamental aspect of
the design of Trellis graphics (which clearly happens to be different
from how you would have designed it, but so what?).

If you want the same limits in every panel even when relation="free",
put in an explicit ylim=c(-0.2, 2) or something similar.
