What does logical AND operator do with label matrices?

In this code, blobs are small blobs within a greater tissue (tissuemask). It's my understanding that the output of watershed, wsh, is a label matrix that labels over 400 different blobs.
wsh = watershed(~(blobs)); % separate any connected blobs
c = imdilate(blobs) & wsh & tissuemask;
c is another mask that contains all three here - my question is, how is wsh treated as a logical binary mask when it contains values from 1 to over 400? How does the AND operator treat a label matrix? Does it just include any nonzero value?

The AND operator treats any nonzero value in "wsh" as true, so specific information about the labels is thrown out when creating "c"
