version control - SVN - Is creating branch from branch from branch on and on wrong? -

situation: have seen practice svn branches created branches , keep on going. example: branch1 created trunk; branch2 branch1; etc. see below idea:

....goes on , on.......branch4--from--> branch3--from--> branch2--from--> branch1--from-->trunk.

so each new branch created latest branch; instead of creating trunk or main.

questions:

1. is kind of practice faulty?
2. will cause issues?
3. is kind of practice followed anywhere?

update: first , third questions have satisfactory answers. help. there issues wary of in particular while following method?

is kind of practice faulty?

no.

will cause issues?

no new types of issues "here , back" merges, compared "trunk-mediator" case, (possible) *n old types (where n amount of synchronized branches)

is kind of practice followed anywhere?

probably yes - it's rather common case , doesn't have exotic , irrational

note: think, using svn 1.8 automatic merges give noticeable amount of benefits in amount of needed operations in final reintegration, comparing pre-1.8 merge --reitegrate
