Left: side, direction 方, right: horizontal person , var. of correct 正. (When sleeping, one must occasionally turn to the other side to avoid pressure & bed sores & circulation problems.)
Mnemonic
The side of the lying person is fine/correct, but he must turn.
This radical can be seen as a person 人 who has the right leg horizontal 一. He is thus lying. (Further radicals with "person" are: sitting 匕, sitting cross-legged 夂, kneeling ⺈, skilled 才, bending マ,卩, slumped 㔾 or husband 夫)
Radical 103 疋 stands for clothing or bales of cloth. In the Hanzi-Trainer, it is used synonymously with the correct 正, because it seems helpful for the explanations and the interpretation clothing/cloth bale would be in conflict with other radicals.
