This section describes the common querying operations, such as adding, deleting, and synchronizing system parameters profiles.
The author says:
This expression is not correct
Adding, deleting and synchronizing are not included in the query operation. These four operations are parallel.
These are not querying operations: adding, deleting, and synchronizing system parameters. 'querying operations' means, asking about/finding out more information about.
querying information about (something)
Notice the comma below. It separates 'querying operations about' from 'adding'.
Ex: ..querying information about, adding
If 'adding' were the grammatical object of 'about' there wouldn't be a comma there.
Ex: ..querying information about adding, deleting, ...
All the best.
