Entity Ref field being rendered in one content type, vs only target_id in another.

I'm using a certain entity ref field across multiple content types, and was creating a token for it to use with the metatag module when I noticed that in my blog type, when I "dpm($node);" I have access to "$node->my_field['und'][0]['entity']->my_field2['und'][0]['uri']);" vs only "$node->my_field['und'][0]['target_id'];" in my article content type. I checked the field settings in both content types, and they are identical. Why would I have access to the rendered entity in one content type and not the other?

Thank you,
Sean
