What's the difference between:

onclick="thankyoulike.del({$post['pid']}, {$post['tid']}); return false;"

onclick="return thankyoulike.del({$post['pid']}, {$post['tid']});"

I was using 2nd version so far cuz I had different styling for buttons so I was copying the entire code when I update the plugin. I just noticed beside styling that part also looks different than original. When I change it to original (revert diff) Ajax doesn't work properly (when I like a message tyl list disappears)
