Hi,
The recording process and the user interface used in TruClient and Web(http/html) protocol are different.
In TruClient you have: TruClient Sidebar which contains all the tools you need to develop your Ajax TruClient scripts, Application Browser Window to develop and replay your script interactively etc.
Ajax TruClient scripts are recorded on the user level, therefore there are no correlations however the main challenge becomes object identification.
Ajax TruClient scripts are replayed at the user level, therefore each Vuser requires a browser instance with loaded DOM and Javascript. This makes resource footprint larger than the Web (transport based) protocol which means that you will need more and stronger LGs for execution of a load tests.
I would suggest you to review LoadRunner user guide for the version of LR you are using, where you can find a detailed explanation of how the Web(http/html) and TruClient protocol recording is done.

Kind regards,
