Workflow Reassign Question - PO

I have, probably, a simple question to ask.

Our PO Workflow approvals are as such

Anything below $2,500 automatically approved

EDE_WF_PO_LEVEL1 - approves $2500.01 - $10,000

EDE_WF_PO_LEVEL2 - approves $10,000.01 - $50,000

EDE_WF_PO_LEVEL3 - approves $50,000.01 - above

LADAMS, EDE_WF_PO_LEVEL2, has created an alternative user to receive his worklist temporarily, IJOHNSON, EDE_WF_PO_LEVEL1.

Since IJOHNSON has a different approval level as LADAMS, won't this cause problems?

Should he have reassigned worklist to another user with same approval level?

The particular PO in question is for $4936.32 which is approval level 1, which IJOHNSON has.  But when the PO was routed for approvals, it skipped approval levels 1,2,3 because it said no approval Level 1, 2, and 3 was found.
