How to reduce load time of dolphin 7 - part 2

Need a bit of clarity. If someone could look this over a tell me why, after putting in the following code, GTmetrix.com still shows the add expires headers as not installed. I applied this to my htaccess in the root. I will attach screen shot of report. My site is vunderba dot com. When I applied it I see a fluctuation in performance between 92-94 page speed and 72-75 on yslow. Goes up and down with code as is. Running 7.1.3 and have both deflate and expire mods on server.

AddType application/vnd.adobe.air-application-installer-package+zip .air
AddType application/x-shockwave-flash .swf
