Could also be the flow of the house. Every house I’ve been in where the washer and dryer are side by side, the washer has been closer to the entrance of the wash room and the dryer is farther (and usually towards the back door). My thought process would be dump the clothes in the washer and then kick the basket in front of the dryer to pull them out later and get it more out of the walking path. (unless there’s room on top of the dryer)
