I’m a little confused about what your issue is. What is your end goal? Are you trying to get a logo open from AE to Premiere without exporting it? If so, use Adobe Dynamic Link in Premiere (File –> Adobe Dynamic Link–> Import After Effects Composition) and import the logo composition from your After Effects file.
As far as H.264 in AE, if you have Premiere and/or a CC subscription, you have Adobe Media Encoder. To export H.264 from After Effects, export to Media Encoder instead of adding to your render queue.
Hope that helps.
