if template A contains "<includeonly>subst:</includeonly>#ifexist:{{FULLPAGENAME}}| true | false }}" and we first create page B with "{{subst:A}}", then the result will be "false", if we then re-edit page B, and again write "{{subst:A}}, the result is still "false".
forgot that variables isn't transparent to subst (which they should be imo)
