Can you submit a runnable test case reproducing the issue? I am testing current master branch and everything works as expected. Note that MultipleHiLoPerTableGenerator executes SQL statements against JDBC connection provided down the line by MultiTenantConnectionProvider (skipped few layers; look at JdbcIsolationDelegate#delegateWork(WorkExecutorVisitable, boolean), JdbcIsolationDelegate#jdbcConnectionAccess() should evaluate to ContextualJdbcConnectionAccess). TableGenerator has nothing to do with multi-tenancy.
