docs: Uses variator functionality to test selected variant on more terms. This
  is used when variant is represented by more terms. Since usually only one
  term per variant is used, only one multiple variant is allowed per
  variator and should be placed as the last one
  
  @param variant
  Number of variant (last variant in variator)
  @param properties
  Properties map where to store property type
  @param values
  Values map where to store property value
  @param terms
  Array of terms used for variant
  @return <code>true</code> in case of success, <code>false</code>
  otherwise
