How can the aircon be at the same temperature for both heating/cooling modes and feel different?

There are a lot of good answers here. Another thing to remember is that when you heat air, the mass of water stays the same, so the relative humidity drops. Cool air is significantly drier (in terms of water mass) than warm air.
As an example, if you maintain 74 degrees, air conditioning should drop the dewpoint to approximately 52 degrees, which is a relative humidity of about 46%. But if it’s 35 degrees outside, your dewpoint can’t be higher than 35, and is probably much lower. This means the relative humidity is only 24% or lower, a very noticeable difference that will certainly impact comfort.
