Matching results in IGI index to "images" of records online

I found a possible match (Maria "Virginia" Fernandez, born 04 Jul 1885 to Pantaleon Fernandez and Marianna/Maceana Macias) in the IGI index with the christening listed as San Francisco de Asís, Tizapán el Alto, Jalisco, Mexico, when searching for my husband's great-grandmother. However, when I "browse" the online records for San Francisco de Asís, Tizapán el Alto that are available, I can find the correct baptisim year, but she doe not seem to be in the book. I found this with her sister Maria Jacinta Fernandez as well. I did inquire at Familly Search.org, and they inidcated that those records were indexed, but not online yet. Wouldn't the San Francisco de Asís, Tizapán el Alto, baptism images online be the same as those in the film?

I will certainly order the film, but was a bit confused since I expected the images of the baptism books from San Francisco de Asís, Tizapán el Alto to be the same in any format.
