AWS Glue, multiple bookmarks within same job?

Question

Lets say I have a script that is loading multiple frames with different schemas

job.init()
    
DefinitionDyf = glueContext.create_dynamic_frame_from_options(connection_type = "s3", connection_options = {"paths": [DefinitionPath], "recurse": True}, format = "csv",
     format_options= {'withHeader': True}, transformation_ctx="DefinitionBookmark")
    
    
TypeDyf = glueContext.create_dynamic_frame_from_options(connection_type = "s3", connection_options = {"paths": [TypePath], "recurse": True}, format = "csv",
     format_options= {'withHeader': True}, transformation_ctx="TypeBookmark")

I do some transformations and then I wrote to another bucket and I end the script with

job.commit()

Would both bookmarks be updated or just the first one? Is it recommended to split up bookmarks like this? most of the examples I saw only had one bookmark for each job.
