Why am I getting different results from two servers that located in the same destination network?

You're leaving out a crucial piece of information, which is the subnet mask. You're making an incorrect assumption that these two hosts are in the same network/subnet based solely on the octet values without considering the subnet mask that each host is using. They could very well be in different networks.

Think of a house address. If I told you that I lived at 123 Smith Street would you know where my house is? No, you wouldn't. If I told you that I lived at 123 Smith Street in Smithtown would you know where my house is? No, you wouldn't. If I told you that John Smith also lives on Smith Street would you know if he and I are neighbors? No, you wouldn't. Even if I told you that John Smith also lives in Smithtown it's not possible for you to know if we're neighbors. If I told you that I lived at 123 Smith Street in Smithtown, Michigan 46123 would you know where my house is? Yes, you would. If I then told you that John Smith lives at 361 Smith Street in Smithtown, Michigan 46123 would you know if we're neighbors? Yes, you would know that we are in fact neighbors and live in the same neighborhood.

Knowing the IP address without knowing the subnet mask is like knowing my house address and street name without knowing the city, state and zip code. It's incomplete and doesn't give you enough information to know where my house is, or if a particular person also lives in my neighborhood.

The same company host doesn't means that they are on the same network architecture... so route and ping might be different if they are connected to different network elements (proxy, firewall, loadbalancers...). As they are on different subnetworks, they also might be in different Datacenters which means different physical location, so the ping time might be different

If you are getting different traceroute results, it is because the routing is being handled differently. This could be because the hosts are not on the same network (as Paul's first comment under your question noted... I am agreeing with his comment... many companies these days are international, so being part of the same company doesn't necessarily mean that traffic will get routed to the same spot).

Another possible reason is a router might just be misconfigured. To really troubleshoot this might require having access to the routing tables of the router that provides the different route. If that is just some random ISP, you probably don't have access to that routing table.
