There are a number of reasons why this can occur. One of them being that Presto internally has many caches; It is possible some the caches or being filled during execution which increases the memory utilization. It should not be an issue though as they are flushed when memory is required. Additionally, it could also just be JVM garbage collection not kicking it to reduce the heap footprint.
Are you seeing memory-related errors when executing later queries? More specifics would help.
