basic.deliver is an AMQP 0.9.1 method RabbitMQ uses to "push" messages to
clients.
Messages then may be acknowledged automatically (immediately) or manually
(when the client sees fit).

basic.get is another operation when a client fetches a message
synchronously,
very similar to HTTP GET. Again, messages may be ack-ed manually in this
case
but it is relatively rare to do so, I believe, so in most cases you will
see automatic acknowledgements
used with basic.get.

My guess would be because of the different acknowledgement modes used.

Please take a look at
http://www.rabbitmq.com/tutorials/amqp-concepts.htmlwhich explains
what I've said above in more detail.
