Why does SSMS's line counting often get messed up?

I’m trying to get some code to run with the time tested ‘execute, google the red text, do what SO says, repeat’ method and I’ve noticed that the error handler’s line counting is often wrong.

For exaple, in this stored procedure it will be correct:

    create procedure why_it_be_like_dis

    as

    select * from INFORMATION_SCHEMA.tables where column_name like '%bananna%'

But in a real world example, it will be off:

Question: Why don’t the line numbers always match?

error message:

Msg 207, Level 16, State 1, Procedure delete from_and_load, Line 21 [Batch Start Line 7]
Invalid column name ‘SRGY_STM_LKP_ID’.
