TABSTRIP_ITEM vs TABSTRIP - When to use

Hello folks,

I'm having a hard time trying to understand when one will be referenced or the other. While writing my macros these guys appear as a complement of tabsTAXI and is used to change tabs inside a window, but sometimes it's just TABSTRIP and sometimes its TABSTRIP_ITEM, sometimes even on the same tab reference, and at this point I'm afraid to log onto SAP tomorrow and what was TABSTRIP yesterday is TABSTRIP_ITEM today.

Below is an example that I recorded, it just go from tab 5 to 6 and change the line. You can see that tab 5 sometimes has the ITEM append and sometimes not.

Can anyone shed somelight here? Is there  a way to predict when it will be one and when it will be the other?

Thank for reading and maybe reply =)
