Is there a better way to achieve this task using awk?
What do you mean by better way? Most efficient? The shortest or most cryptic? Your solution appears to work based on your input/output after implementing #2 and #4 in my last post and is readable. Surely there are other alternatives on how to do it with awk or other commands/utilities but without further clarification on the requirements or what you mean by a better way, it's hard for us to make suggestions.

Your requirement
Quote:
if the sequence in the even line is shorter than 7 , both, the odd line and "id" should be removed
does not match your desired output results as the below line on your input file does not meet this condition (i.e. it's not shorter than 7) and should therefore appear in the output file (your output file does not have it).

btw...Editing/correcting your prior posts based on suggestions made in subsequent posts makes it difficult to follow the history of the posts.
