Careful Coding Considerations

I'm pretty sure this stored procedure is fairly vanilla, with some minor adjustments made over the years, but it's been requested that we remove the error that gets raised when activity has taken place in a record since it appeared in the potential dupes table.  The relevant - or what I believe is relevant - code block says:

---------------------------------  CODE BLOCK STARTS HERE  -------------------------------------

--If any change has taken place to either record since they were entered into the t_potential_dups
--table, log exception and skip.

--First check if this pair is coming from t_potential_dups table or manually picked
--RW #4094, added identify_method to manually added criteria

if substring(@criterion, 1, 10) = '!@#$CUSTOM' or @identify_method in (-1,-2) GOTO StartMerging

declare @last_activity_dt datetime
declare @dupTable_dt datetime

select @last_activity_dt = last_activity_dt
from [dbo].t_customer
where customer_no = @original_no

select @dupTable_dt = last_update_dt
from [dbo].t_potential_dups
where customer_no = @original_no

If @duptable_dt IS null or @last_activity_dt > @dupTable_dt
Raiserror('Merge aborted! Reason: Constituent activity took place on kept customer_no %d since this was scheduled for merging.', 11, 2, @original_no)

select @last_activity_dt = last_activity_dt
from [dbo].t_customer
where customer_no = @duplicate_no

select @dupTable_dt = last_update_dt
from [dbo].t_potential_dups
where customer_no = @duplicate_no

If @duptable_dt IS null or @last_activity_dt > @dupTable_dt
Raiserror('Merge aborted! Reason: Constituent activity took place on deleted customer_no %d since this was scheduled for merging.', 11, 2, @duplicate_no)

---------------------------------  CODE BLOCK ENDS HERE  -------------------------------------

Now, am I correct in assuming that the If statements regarding activity dates, and the subsequent Raiserror statements that follow them, can be commented out and that's that? I'm also assuming that the select statements that follow the Raiserror statements will run regardless of the If statements' logic since there is no BEGIN and END statements to make them a block contingent upon the preceding If statement. Or do I need to comment out the entire block from one If statement to the next? Am I making sense?
