@Mohammad the underyling issue is one that I think we have discussed before in another context.
TiddlyWiki filters distinguish between no results from a filter step, and an empty string as a result. When there is no result from a filter step, like with get[text] on a non-existent tiddler, the next filter step receives no input and therefore the entire filter run will have no output. However, by using else[] we specify an empty string as the input to the next step if the previous step had returned no result. This allows the addsuffix[] step to return a result. This is the same reason why we have the is[blank] operator, to distinguish between no result, and an empty string as a result.
