Oh boy! I must say that Seam deployments in AS-5.0.x and AS-5.1.0 have (known) issues. As you noticed, 5.0 did not identify the changes to .xhtml and did not redeploy. AS-5.1.0 does the exact opposite, it finds that Seam deployments need to be redeployed (for no valid reason) :) Fortunately there's a workaround.
