Same ip in two different hosts but with different netmask, will work?

If I configure a network with 10.0.0.0/16 it's range is from 10.0.0.1 to 10.0.255.254, so a host with an IP like 10.0.0.2/16 is ok.

But if I configure another network with IP alias (like IP address add 10.0.0.0/24 brd + dev eth0) and another host is configured with an ip like 10.0.0.2/24.

Will this work? Or it is a conflict?. The IPs are the same, but with different netmasks.

Excuse me the lack of testing but I don't have how to test this.
