Network IP Range Lingo Question

I'm a network engineer, have been for 3 years. I had a conversation with a coworker and we were discussing IP ranges. We have a /16. I said when reworking our IP range we wouldn't use the top half (thinking 145.138.255.254 instead of like the lower half 145.138.10.5). He then said yeah we don't want to use the bottom half, to which he thinks means the higher half of the /16 range such as 145.138.128 on up. Isn't that the top or higher half of the IP range?
