Plugin cannot update child versions when pom path specified

Project structure:

    ├── moduleA
    │   └── submoduleB

parent pom.xml

  <groupId>org.example</groupId>
  <artifactId>parent</artifactId>
  <packaging>pom</packaging>
  <version>1.0-SNAPSHOT</version>
  <modules>
    <module>moduleA/pom.xml</module>
  </modules>

moduleA pom.xml

  <parent>
    <artifactId>parent</artifactId>
    <groupId>org.example</groupId>
    <version>1.0-SNAPSHOT</version>
  </parent>
  <modelVersion>4.0.0</modelVersion>

  <artifactId>moduleA</artifactId>
  <packaging>pom</packaging>
  <modules>
    <module>submoduleB/pom.xml</module>
  </modules>

submoduleB pom.xml

  <parent>
    <artifactId>moduleA</artifactId>
    <groupId>org.example</groupId>
    <version>1.0-SNAPSHOT</version>
  </parent>
  <modelVersion>4.0.0</modelVersion>

  <groupId>org.example.moduleA</groupId>
  <artifactId>submoduleB</artifactId>

Command:

mvn org.codehaus.mojo:versions-maven-plugin:2.8.1:set -DnewVersion=123456

Expected behaviour:
All 1.0-SNAPSHOT versions to be replaced with 123456

What happens:
Only versions in root pom.xml and moduleA/pom.xml is updated, the one in submoduleB/pom.xml stays the same

Note:
When pom.xml paths not specified, plugin works correctly and updates all of them successfully
