What is the difference between disabled and enabled of "Wait for execution to complete?"?

Hi, everyone.

My work has these 3 steps:
< 1step >
To register transactions to the transaction table.

< 2step: rowTotal >
To sum the transaction amount with each account by running the process of Call a webhook.

< 3step: subTotal >
To sum the rowTotal of the first step of the bot to the subTotal by running the process of Call a webhook.

※ The transaction table is as follows.

※ The report table is as follows.

※ I have 5 bots. And this is the result of running each bot.

no	the name of each bot	the process of each bot	Wait for execution to complete?	report table after running each bot
1	rowTotal	- rowTotal	n/a
2	subTotal	- subTotal	n/a
3	rowTotal_subTotal	- rowTotal - subTotal	n/a
4	rowTotal_triggerSubTotal_disabled	- rowTotal - triggerSubTotal	disabled
5	rowTotal_triggerSubTotal_enabled	- rowTotal - triggerSubTotal	enabled

[Question] 

Like the result, there is no difference between no.4(disabled) and no.5(enabled).

BTW, what I expect from disabled is this:

What is the difference between disabled and enabled of "Wait for execution to complete?"?

Thank you.
