IgniteCache.size() for different cache show the same number

[kcheng.mvp]

here is my code 

    public IgniteCache<ArticleAffKey, Comment> comment() {
        return igniteSpringBean.getOrCreateCache(IgDef.DOCS);
    }

    public IgniteCache<CommentAffKey, Reply> reply() {
        return igniteSpringBean.getOrCreateCache(IgDef.DOCS);
    }


I put 10 records to  *IgniteCache<ArticleAffKey, Comment> *

but when I call  IgniteCache<CommentAffKey, Reply>.size() it returns 10,
even I did not put any *Reply* to cache.

I suppose it should return 0, as I did not put any *Reply* to cache.

is this correct?
