The behaviors for bees returning with that which they "think" is propolis
are entirely different than those for which they "think" the material is pollen. 

Not sure about that. In both cases, they fail to evaluate the content and respond on cues that are only partly valid. Bees are unable to assess neither the nutritional content of pollen nor the bactericidal value of resins. The parameters that guide them are approximate and lead them to occasionally collect bogus products. Overall, the criteria are effective nonetheless.
