I tried this transformation  this way..can grignard reagent prepare from this way?isn't that grignard rect with the carbonyl group?

The so called ”actuall product" in this reference containes both a aldehyde and a Grignard group in the same molecule, this is wrong, off course.

I sent an error notice to the owner of the Portal, but I noticed that responding to such comments sometimes appears after 2 years. This wrong structure should look like more to me:

This error in the diagram does not mean, however, that the information on the protection of the carbonyl group in Grignard reactions is incorrect.
