I'm not sure as there is no DTD for logback.xml due to the complexity of it. It probably reconfigures the root logger for each element it sees, but I'm really not going to dig through the code to confirm that.
If you look at Chp 3 Configuration Syntax <https://logback.qos.ch/manual/configuration.html#syntax>, you'll notice a diagram explaining the high-level elements and their cardinality within the configuration file with only a single root element. Chp 7 Filters has an entry on ThresholdFilter filter <https://logback.qos.ch/manual/filters.html#thresholdFilter>, which is exactly what you need.
