in the scl code written in screenshot
Line 1 condition is false
but still the program checking the line 2 condition and says it is true

i had this understanding that if the condition is not true then the program will skip line 2

I presume the status values are from the previous cycle where the first if-condition was true and so the second was processed.

To indicate this, the status values are grey instead of black.

Also you can write:

If MyBool1 and NOT MyBool2 etc

Makes it easier to follow for boolean evaluation, you dont need the '=1'

Yes i think that is correct , if it was true in black then the montime will be updated to 25000 but it is not updated
but this is confusing the condition is not true at the moment then instead of showing true in grey should be showing false in black
