Here’s another question.y Let’s supppose I’ve got this code:

When the url is using a segment2, does the template queries weblog1 and weblog2?
I think it should not but on the debugging it appears as it does.
Thank you.

Yes- with complex conditionals, both queries happen- it’s just affecting display.  However, with simple conditionals, the conditionals are parsed earlier.  So you only get one query using simple conditionals, both queries with complex.  (Slightly simplified, but that’s the gist.)

Make sense?

I see. No sense. Also asking for the segment parameter should a be simple conditional.

It’s the ‘else’ that makes it a complex conditional.  So:

That would be two simple conditionals- and the weblog tag would only run once- for the one that meets the conditions.  Basically?  Complex and simple conditionals fall at different spots in the parse order- thus they will behave differently.
