一个英语句子问题He stood leaning against the wall.意思是他靠着墙站着,但是,again

Against is a preposition and lean is a verb.
You could say he stood against the wall,it's correct grammar but doesn't make much sense,stand against the wall?How do you do that?
The original sentence was meant to mean:Leaning against the wall,he stood.Which bascially means he leans against the wall.Rather,you could not say he against the wall 'cause then the s doesn't have a verb.At least,he is against the wall.
Edit:
That's correct,like I say:Thinking of you,I feel lonely.(Being) exhausted,I went home.

我是这样理解的：意思虽然一样，但是，against the wall,只是表征站的方式，在句子中做方式状语；如果是leaning against the wall 的话，是和stood 同时进行的，表征伴随，在句子中是伴随状语，当然-ing 是主动的意思啊！当然去掉也是可以的。

lean 有倾斜的靠着的意思吧，就更加表达的形象了
他站着倾斜的靠着墙
