Coleman, 23, has started each of the Blues' last three games in the position, impressing with a forward-thinking approach reminiscent of Baines' own.
Baines told evertontv: "It's part of the game now, isn't it? Full-backs are expected to attack a bit more and are expected to provide assists or even goals.
"That's what Seamus is all about as well. He's a really good full-back.
"He's been doing a job in the midfield role, which he's very good at as well, but I think naturally he probably feels his home is at full back and we've seen that in the last few games. He's done really well."
